Chapter1 Android體系與系統架構

Android 高富帥 Google Linux Open Source

四層：Applications/Application Framework/Libraries+Android Runtime/Linux Kernel

Android 5.X起ART取代Dalvik Dalvik運作時編譯 ART安裝時編譯

PackageManager/ResourceManager/ActivityManager/WindowManager/ViewSystem/NotificationManager/LocationManager/TelphonyManager/Content Provider/XMPP Service

Android NDK APP AndroidManifest/Dalvik Classes/Resource Bundle/Libraries & JNI

Android SDK APP AndroidManifest/Dalvik Classes/Resource Bundle

四大元件：Activity/BroadcastReceiver/ContentProvider/Service

Intent信使

上下文Context：Application/Activity/Service都繼承自Context ApplicationContext是全局的上下文 getApplicationContext()

Android系統源碼：http://androidxref.com/ Makefile機制

Chapter2 Android開發工具新接觸

工欲善其事，必先利其器

IDE Integrated Development Environment 內建開發環境

Eclipse vs Android Studio(2013年I/O大會)

http://www.androiddevtools.cn

Case sensitive completion

ADB指令

adb version

adb install -r F:\test.apk

adb push D:\test.apk /system/app/

adb push <local> <remote>

adb pull <remote> <local>

adb shell

adb remount

adb shell

rm *.apk

adb shell input keyevent 3

adb shell input touchscreen

adb shell input touchscreen swipe

pm/am

adb指令來源于\system\core\toolbox 和 \frameworks\base\cmds

Chapter3 Android控件架構與自定義控件詳解

Android中每個控件都會在界面中占得一塊矩形區域 ViewParent-ViewGroup/View 樹形結構

findViewById()深度優先周遊 setContentView()

Activity(PhoneWindow(DecorView(TitleView+ContentView))) 其中DecorView為根View WindowManagerService接收所有View的監聽事件

ContentView是一個id為content的FrameLayout TitleView一般為ActionBar Container requestWindowFeature(Window.FEATURE_NO_TITLE)要在setContentView()之前

ActivityManagerService進行Activity的生命周期回調

View的測量：onMeasure()

MeasureSpec是一個32位的int值高2位為測量模式低30位為測量的大小

測量模式：

EXACTLY 适用于 android:layout_width="100"或者match_parent

AT_MOST 适用于wrap_content

UNSPECIFIED 适用于自定義View時想多大就多大

@Override

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){

//super.onMeasure(widthMeasureSpec, heightMeasureSpec);

setMeasuredDimension(measureWidth(widthMeasureSpec), measureHeight(heightMeasureSpec));

}

private int measureWidth(int measureSpec){

int result = 100;

int specMode = MeasureSpec.getMode(measureSpec);

int specSize = MeasureSpec.getSize(measureSpec);

if(specMode == MeasureSpec.EXACTLY){

result = specSize;

}else if(specMode == MeasureSpec.AT_MOST){

result = Math.min(result, specSize);

}

return result;

}

View的繪制：onDraw()

Canvas對象其它地方Canvas canvas = new Canvas(bitmap); canvas.drawXXX();

ViewGroup的測量：周遊子View

ViewGroup的繪制：dispatchDraw()

自定義View：擴充現有控件/組合實作控件/重寫View實作

onFinishInflate()/onSizeChanged()/onMeasure()/onLayout()/onDraw()/onTouchEvent()

定義屬性：res/values/attrs.xml <resources><declare-styleable name="TopBar"><attr name="title" format="string"/></declare-styleable></resources>

TypedArray ta = context.obtainStyledAttributes(attrs, R.styleable.TopBar);

ta.recycle();

xmlns:custom="http://schemas.android.com/apk/res-auto"

重繪：invalidate();/postInvalidateDelayed(300);

自定義ViewGroup：int count = getChildCount(); View childView = getChildAt(i);

事件攔截處理機制

MotionEvent ACTION_DOWN ACTION_MOVE ACTION_UP

public boolean dispatchTouchEvent(MotionEvent ev);

public boolean onInterceptTouchEvent(MotionEvent ev);//View沒有此方法

public boolean onTouchEvent(MotionEvent ev);

流程：Adispatch->Aintercept->Bdispatch->Bintercept->Viewdispatch->ViewonTouch->BonTouch->AouTouch

誰攔截誰處理，處理完就回調

Chapter4 ListView使用技巧

public class DataAdapter extends BaseAdapter{

private ArrayList<String> mDatas;

private LayoutInflater mInflater;

public DataAdapter(Context context){

mDatas = new ArrayList<>();

mInflater = LayoutInflater.from(context);

}

@Override

public int getCount(){return mDatas.size();}

@Override

public Object getItem(int position){return mData.get(position);}

@Override

public long getItemId(int position){return position;}

@Override

public View getView(int position, View convertView, ViewGroup ){

ViewHolder holder = null;

if(convertView == null){

convertView = mInflater.inflate(R.layout.item_content, null);

holder = new ViewHolder();

holder.content = (TextView)convertView.findViewById(R.id.content);

convertView.setTag(holder);

}else{

holder = (ViewHolder)convertView.getTag();

}

holder.content.setText("use ViewHolder cache");

return convertView;

}

public final class ViewHolder{

public TextView content;

}

設定分隔線：android:divider="@android:color/darker_grey" android:dividerHeight="10dp"

隐藏分隔線：android:divider="@null"

隐藏滾動條：android:scrollbars="none"

取消Item的點選效果：android:listSelector="#00000000" 或 android:listSelector="@android:color/transparent"

顯示在第幾項：listView.setSelection(N);listView.smoothScrollXX();

notifyDataSetChanged();

空ListView可以設定setEmptyView()來顯示内容為空時的提示

ListView的滑動監聽：GestureDetector/VelocityTracker onTouchListener/onScrollListener

firstVisibleItem/visibleItemCount/totalItemCount

overScrollBy()中maxOverScrollY改為一個數字就可以彈性十足了

自動顯示隐藏的ListView

//添加頭防止ActionBar引藏了第一個Item

View header = new View(this);

header.setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, (int)getResources().getDimension(R.dimen_abc_action_bar_default_height_material)));

mListView.setHeader(header);

mTouchSlop = ViewConfiguration.get(this).getScaledTouchSlop();//擷取最低滑動距離

View.OnTouchListener mOnTouchListener = new View.OnTouchListener(){……};//動畫用屬性動畫

不同布局的ListView

getItemViewType()/getViewTypeCount()

Chapter5 Android Scroll分析

滑動一個View本質上就是移動一個View改變其目前所處位置

Android坐标系：螢幕左上角(0, 0) 右 X正下 Y正 getLocationOnScreen(int[] location); getRawX()/getRawY()

視圖坐标系：相對于父視圖 getX()/getY()

MotionEvent ACTION_DOWN/ACTION_UP/ACTION_MOVE/ACTION_CANCEL/ACTION_OUTSIDE/ACTION_POINTER_DOWN/ACTION_POINTER_UP

View提供的擷取坐标的方法：getTop()/getLeft()/getRight()/getBottom()

MotionEvent提供的方法：getX()/getY()/getRawX()/getRawY()

實作滑動的八種方法：

layout()/offsetLeftAndRight()和offsetTopAndBottom()/LayoutParams(getLayoutParams()/setLayoutParams)/scrollTo與scrollBy

Scroller/屬性動畫/ViewDragHelper(說好八種隻有七種還有一種，你想想)

Chapter6 Android繪圖機制與處理技巧

螢幕大小：螢幕對角線的長度，機關寸，如5.36寸

分辨率：螢幕的像素點數，720*1280指寬有720個像素點高有1280個像素點

PPI：Pixels Per Inch或DPI，Dots Per Inch 對角線像素點數除以螢幕大小

hdpi:240 / 480 X 800

dp/sp

public class DisplayUtil{

public static int px2dip(Context context, float pxValue){

final float scale = context.getResources().getDisplayMetrics().density;

return (int)(pxValue / scale + 0.5f);

}

public static int dip2px(Context context, float dipValue){

final float scale = context.getResources().getDisplayMetrics().density;

return (int)(dipValue * scale + 0.5f);

}

public static int px2sp(Context context, float pxValue){

final float fontScale = context.getResources().getDisplayMetrics().density;

return (int)(pxValue / fontScale + 0.5f);

}

public static int sp2px(Context context, float spValue){

final float fontScale = context.getResources().getDisplayMetrics().density;

return (int)(spValue * fontScale + 0.5f);

}

//TypedValue類也可以進行轉換

protected dp2px(int dp){

return (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, getResources().getDisplayMetrics());

}

protected sp2px(int sp){

return (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, sp, getResources().getDisplayMetrics());

}

2D繪圖：Canvas/Paint

Android XML繪圖：<bitmap/> <shape/> <layer-list/> <selector/>

Canvas.save()//類似儲存圖層

Canvas.restore()//類似合并圖層

Canvas.translate()//平移坐标原點

Canvas.rotate()//翻轉坐标原點

saveLayer()/saveLayerAlpha()/restore()/restoreToCount()

Bitmap位圖ARGB

色彩矩陣：ColorMatrix 4X5 一維數組存儲矩陣乘法 RGBA 改變系數改變偏移量

色調：setRotate()/飽和度：setSaturation()/亮度：setScale()

mImageView.setImageBitmap(ImageHelper.handleImageEffect());

paint.setColorFilter(new ColorMatrixColorFilter(imageMatrix));

像素點分析：

bitmap.getPixels(pixels, offset, stride, x, y, width, height);

bitmap.setPixels(newPx, 0, width, 0, 0, width, height);

Android圖像處理之圖形特效處理Matrix 3x3

Translate/Rotate/Scale/Skew

像素塊分析：drawBitmapMesh()

畫筆特效處理：PorterDuffXfermode

Shader着色器：BitmapShader/LinearGradient/RadialGradient/SweepGradient/ComposeShader

PathEffect

public class SurfaceViewTemplate extends SurfaceView implements SurfaceHolder.Callback, Runnable

surfaceCreated()/surfaceChanged()/surfaceDestroyed()/run()

private SurfaceHolder mHolder;

private Canvas mCanvas;

private boolean isDrawing;

mHolder = this.getHolder();

mHolder.addCallback(this);

mCanvas = mHolder.lockCanvas();

mHolder.unlockCanvasAndPost(mCanvas);

GenymotionChapter7 Android動畫機制與使用技巧

Frame Animation（drawable目錄裡frame.xml）/Tween Animation(anim目錄裡tween.xml)

Animation架構定義了AlphaAnimation/RotateAnimation/TranslateAnimation/ScaleAnimation四種動畫方式和AnimationSet動畫集合

AlphaAnimation aa = new AlphaAnimation(0, 1);

aa.setDuration(1000);

//aa.setAnimationListener(new Animation.AnimationListener(){……});

view.startAnimation(aa);

Animator架構AnimatorSet/ObjectAnimator

ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationX", 300);

animator.setDuration(300);

animator.start();

//操作對象必須有getter/setter

//translationX/translationY/rotation/rotationX/rotationY/scaleX/scaleY/pivotX/pivotY/x/y/alpha

private static class WrapperView{

private View mTarget;

public WrapperView(View target){

mTarget = target;

}

public int getWidth(){

return mTarget.getLayoutParams().width;

}

public void setWidth(int width){

mTarget.setLayoutParams().width = width;

mTarget.requestLayout();

}

WrapperView wrapper = new WrapperView(mButton);

ObjectAnimator.ofInt(wrapper, "width", 500).setDuration(5000).start();

PropertyValuesHolder pvh1 = PropertyValuesHolder.ofFloat("translationX", 300);

PropertyValuesHolder pvh2 = PropertyValuesHolder.ofFloat("translationY", 300);

ObjectAnimator.ofPropertyValuesHolder(view, pvh1, pvh2).setDuration(3000).start();

ObjectAnimator繼承自ValueAnimator

ValueAnimator animator = ValueAnimator.ofFloat(0, 100);

animator.setTarget(view);

animator.setDuration(1000).start();

animator.addUpdateListener(new AnimatorUpdateListener(){……});

一個完整的動畫具有start repeat end cancel四個過程

animator.addListener(new AnimatorListener(){……});

animator.addListener(new AnimatorListenerAdapter(){……});

AnimatorSet set = new AnimatorSet();

set.setDuration(1000);

set.playTogether(animator1, animator2, animator3);

set.start();

//playTogether()/playSequentially()/before()/after()

animator目錄下animator.xml

<objectAnimator></objectAnimator>……

Animator animator = AnimatorInflater.loadAnimator(this, R.animator.scalex);

animator.setTarget(mView);

animator.start();

view.animate().alpha(0).y(300).setDuration(1000).widthStartAction(*).withEndAction(*).start();

Android布局動畫android:animateLayoutChanges="true"或者LayoutAnimationController

Interpolators插值器定義動畫的變化速率線性加速度

自定義動畫：實作applyTransformation的邏輯并Override initialize() 主要是Matrix m = t.getMatrix();

SVG矢量動畫機制（5.X）Scalable Vector Graphics可伸縮矢量圖形使用XML定義圖形 W3C标準

<path>标簽指令：M/L/H/V/C/S/Q/T/A/Z 大寫絕對定位參照全局坐标系小寫相對定位參照父容器會标系

http://editor.medhod.ac/

VectorDrawable/AnimatedVectorDrawable

group-path

<vector xmlns:android="http://schemas.android.com/apk/res/android"

android:height="200dp"

android:width="200dp"

android:viewportHeight="100"

android:viewportWidth="100">

<group

android:name="test"

android:rotation="0">

<path

android:fillColor="@android:color/holo_blue_light"

android:pathData="M 25 0 a 25 25 0 1, 0 50, 0" />

</group>

</vector>

AnimatedVectorDrawable如同膠水一樣連接配接VectorDrawable和ObjectAnimator <animated-vector/>

(imageView.getDrawable()).start();開始動畫

線圖動畫模拟三球儀軌迹動畫

Chapter8 Activity與Activity調用棧分析

setContentView(View);

Running/Paused/Stopped/Killed

onCreate/onStart/onResume/onPause/onStop/onDestroy/onRestart

onSaveInstanceState()/onRestoreInstanceState

A task is a stack of activities.

android:laaunchMode/standard singleTop singleTask singleTop

Intent.FLAG_ACTIVITY_NEW_TASK

Intent.FLAG_ACTIVITY_SINGLE_TOP

Intent.FLAG_ACTIVITY_CLEAR_TOP

Intent.FLAG_ACTIVITY_NO_HISTORY

clearTaskOnLaunch/finishOnTaskLaunch/alwaysRetainTaskState

Chapter9 Android系統資訊與安全機制

系統的配置資訊：android.os.Build 和 SystemProperty

String board = Build.BOARD;

String os_version = System.getProperty("os.version");

system/build.prop /proc

PM/AM PackageManager/ActivityManager

ActivityInfo封裝了<activity/>和<receiver/>

ServiceInfo封裝了<service/>

ApplicationInfo封裝了<application/>

PackageInfo封裝了<manifest/>

ResolveInfo封裝了<intent/>

packages.xml檔案 /data/system/packages.xml

安全機制五道防線：代碼混淆proguard/AndroidManifest檔案權限聲明檢查/數字證書/UID通路權限控制/沙箱隔離

反編譯：

apktool/dex2jar/jd-gui/AndroidKiller

Chapter10 Android性能優化

UI優化

VSYNC信号觸發重新整理16ms一次 60fps

避免Overdraw

View測量、布局、繪制都是通過對View的周遊進行的

<include />重用Layout

<ViewStub />延遲加載Layout mViewStub = (ViewStub)findViewById(R.id.not_often_use);mViewStub.setVisibility(View.VISIBLE);或View inflateView = mViewStub.inflate();

Hierarchy Viewer

記憶體優化

Android應用沙箱機制 LMK

RAM

寄存器：速度最快，程式無法控制

棧：基本類型的資料和對象的引用

堆：new建立的對象和數組由GC管理

靜态存儲區：一直存在的資料如靜态資料變量

常量池：JVM為每個裝載的類型維護一個常量池

ActivityManager manager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);

int heapSize = manager.getLargeMemoryClass();

調用System.gc()隻是建議系統進行GC但不一定會被采納

Bitmap優化（常見于OOM）：及時回收記憶體（bitmap.recycle()）、圖檔緩存

任何Java類都将占用大約500位元組的記憶體空間建立一個類的執行個體會消耗大約15位元組的記憶體
