Android 自定義loading

前段時間做項目要求添加一個好看的加載動畫，找了很多，都沒有實作功能，後來還是自己找到的方法，具體代碼實作如下：

先看看效果圖

自定義一個loading類：

import android.app.Dialog;
import android.content.Context;
import android.graphics.drawable.AnimationDrawable;
import android.view.Gravity;
import android.widget.ImageView;
import android.widget.TextView;

import com.ycsoft.android.moviebar.R;

public class CustomeProgressDialog extends Dialog {
    private static CustomeProgressDialog customProgressDialog = null;

    public CustomeProgressDialog(Context context) {
        super(context);
    }

    public CustomeProgressDialog(Context context, int theme) {
        super(context, theme);
    }

    public static CustomeProgressDialog createDialog(Context context) {
        customProgressDialog = new CustomeProgressDialog(context,
                R.style.CustomProgressDialog);
        customProgressDialog.setContentView(R.layout.customprogressdialog);
        customProgressDialog.getWindow().getAttributes().gravity = Gravity.CENTER;
        customProgressDialog.setCanceledOnTouchOutside(false);
        return customProgressDialog;
    }

    public void onWindowFocusChanged(boolean hasFocus) {

        if (customProgressDialog == null) {
            return;
        }

        ImageView imageView = (ImageView) customProgressDialog
                .findViewById(R.id.loadingImageView);
        AnimationDrawable animationDrawable = (AnimationDrawable) imageView
                .getBackground();
        animationDrawable.start();
    }

    /**
     * 
     * [Summary] setTitile 标題
     * 
     * @param strTitle
     * @return
     * 
     */
    public CustomeProgressDialog setTitile(String strTitle) {
        return customProgressDialog;
    }

    /**
     * 
     * [Summary] setMessage 提示内容
     * 
     * @param strMessage
     * @return
     * 
     */
    public CustomeProgressDialog setMessage(String strMessage) {
        TextView tvMsg = (TextView) customProgressDialog
                .findViewById(R.id.id_tv_loadingmsg);

        if (tvMsg != null) {
            tvMsg.setText(strMessage);
        }

        return customProgressDialog;
    }

}
           

customprogressdialog.xml布局代碼：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="horizontal">
    <ImageView
        android:id="@+id/loadingImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@anim/progress_round"/>
    <TextView
        android:id="@+id/id_tv_loadingmsg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:textSize="20dp"/>
</LinearLayout>
           

CustomProgressDialog style代碼如下：

<style name="CustomDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    </style>

<style name="CustomProgressDialog" parent="@style/CustomDialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
    </style>
           

progress_round.xml 代碼如下：

<?xml version="1.0" encoding="utf-8"?>
<animation-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="false">
   <item android:drawable="@drawable/progress_1" android:duration="200"/>
    <item android:drawable="@drawable/progress_2" android:duration="200"/>
    <item android:drawable="@drawable/progress_3" android:duration="200"/>
    <item android:drawable="@drawable/progress_4" android:duration="200"/>
    <item android:drawable="@drawable/progress_5" android:duration="200"/>
    <item android:drawable="@drawable/progress_6" android:duration="200"/>
    <item android:drawable="@drawable/progress_7" android:duration="200"/>
    <item android:drawable="@drawable/progress_8" android:duration="60"/>
</animation-list>

CustomeProgressDialog的使用方法

private CustomeProgressDialog customeProgressDialog;

customeProgressDialog = CustomeProgressDialog.createDialog(mContext);
//顯示加載動畫
customeProgressDialog.show();

//加載動畫消失
if (customeProgressDialog != null
                    && customeProgressDialog.isShowing()) {
            customeProgressDialog.dismiss();
            }
