仿的微信總結

看了鴻洋大神做的微信5.1版本的東西，自己模仿着做了一下，現在總結一下。

有相應的代碼，可以下載下傳

微信的第一個RelativeLayout

在裡面攝者一個LinearLayout寬度設定為fill_parent，高度設定為40dp，裡面嵌套一個LinearLayout，這個LinearLayout由一個ImageView,Textview組成

微信的第二個LinearLayout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="50dp"
    android:background="#eee">
<LinearLayout
    android:id="@+id/id_ll_chat"
    android:layout_height="47dp"
    android:layout_width="fill_parent"
    android:orientation="horizontal">
    <LinearLayout android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:layout_weight="1"
        android:orientation="horizontal"
        android:gravity="center">
        <TextView android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:text="聊天"
            android:textColor="#000000"
            android:id="@+id/tl"/>
        </LinearLayout>

    <LinearLayout android:layout_height="fill_parent"
                  android:layout_width="fill_parent"
                  android:layout_weight="1"
                  android:orientation="horizontal"
                  android:gravity="center">
        <TextView android:layout_height="wrap_content"
                  android:layout_width="wrap_content"
                  android:text="發現"
                  android:textColor="#000000"
            android:id="@+id/tf"/>
        </LinearLayout>
        <LinearLayout android:layout_height="fill_parent"
                      android:layout_width="fill_parent"
                      android:layout_weight="1"
                      android:orientation="horizontal"
                      android:gravity="center">
        <TextView android:layout_height="wrap_content"
                  android:layout_width="wrap_content"
                  android:text="通訊錄"
                  android:textColor="#000000"
            android:id="@+id/tt"/>
    </LinearLayout>
    </LinearLayout>
    <ImageView
        android:id="@+id/id_iv_tabline"
        android:layout_width="127dp"
        android:layout_height="3dp"
        android:background="@drawable/tabline" />

</LinearLayout>

這個LinearLayout裡嵌套了三個LinearLayout，這三個LinearLayout裡，每個都有一個TextView，在最後的結尾加一個藍色的條

下面是主avtivity_main

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >
    <include layout="@layout/shangyi"/>
    <include layout="@layout/shanger"/>
    <android.support.v4.view.ViewPager
        android:id="@+id/id_viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
</LinearLayout>

在裡面加入這兩個布局，在加入一個viewpager用于加入下面的可滑動的頁面

下面建立幾個布局檔案

裡面隻有textView，這幾個布局檔案的用處就是為fragment提供模闆，再分别建立相應的.java檔案，

下面我們在MainActivity裡進行設定

先要屏蔽actionbar

我們可以用這幾個方法

1.getActionbar().hide();

2.或在androidmanifest中設定設定android:theme=""

@style/Theme.AppCompat.Light.NoActionBar
