DrawerLayout抽屜布局，現在主流App是越來越多使用DrawerLayout，因為這樣出來的效果是比較炫酷的吧！其實抽屜界面很簡單，沒有網上說的那么復雜，今天我就給大家介紹一種比較簡單的抽屜布局，DrawerLayout，

效果圖：

1:主布局文件（分為2塊，第一塊是主頁面內容，第二塊是抽屜頁面內容，這是固定的，必須是這樣的格式）

<LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"
??? xmlns:tools= "http://schemas.android.com/tools"
??? android:layout_width="match_parent"
??? android:layout_height="match_parent"
??? android:orientation="vertical"
??? android:paddingBottom="@dimen/activity_vertical_margin"
??? android:paddingLeft="@dimen/activity_horizontal_margin"
??? android:paddingRight="@dimen/activity_horizontal_margin"
??? android:paddingTop="@dimen/activity_vertical_margin"
??? tools:context=".MainActivity" >

??? <android.support.v4.widget.DrawerLayout
??????? android :id="@+id/drawer_layout"
??????? android :layout_width="match_parent"
??????? android :layout_height="match_parent">
???????
??????? <!-- 主界面-->
???????
??????? <LinearLayout
??????????? android:id="@+id/content_frame"
??????????? android:layout_width="match_parent"
??????????? android:layout_height="match_parent"
??????????? android:background="#FF0000">

??????????? <Button
??????????????? android:id= "@+id/btn"
??????????????? android:layout_width= "match_parent"
??????????????? android:layout_height= "wrap_content"
??????????????? android:text= "open" />

??????? </LinearLayout >

??????? <!-- 抽屜界面 --> //抽屜頁面可以是一個Fragment，或者是ListView，什么都可以，這里以Fragment為列子，因為Fragment可以添加一個布局文件

??????? <FrameLayout
??????????? android:id="@+id/fragment_layout"
??????????? android:layout_width="match_parent"
??????????? android:layout_height="match_parent"
??????????? android:layout_gravity="start"//從左邊滑動進來，右邊是end，一定要寫，不然沒有效果
??????????? android:background="#9053ff59"></ FrameLayout>
??? </android.support.v4.widget.DrawerLayout >

</LinearLayout >

2:Fragment布局文件

<?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" >
??? <Button
??????? android :layout_width="match_parent"
??????? android :layout_height="wrap_content"
??????? android :text="按鈕一"/>
??? <Button
??????? android :layout_width="match_parent"
??????? android :layout_height="wrap_content"
??????? android :text="按鈕二"/>

??? <Button
??????? android :id="@+id/item_frgment_bt"
??????? android :layout_width="match_parent"
??????? android :layout_height="wrap_content"
??????? android :text="按鈕三"/>

??? <Button
??????? android :layout_width="match_parent"
??????? android :layout_height="wrap_content"
??????? android :text="按鈕四"/>

</LinearLayout >

4：Fragment類

package com.example.yangjie.drawerlayout;

import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;

/**
* Created by Administrator on 2015/10/17.
*/
public class DrawerFragment extends Fragment {
??? @Nullable
??? @Override
??? public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
??????? return inflater.inflate(R.layout.item_frgement,container,false);//將布局文件綁定到Fragment中
??? }

??? @Override
??? public void onViewCreated(View view, Bundle savedInstanceState) {
??????? super .onViewCreated(view, savedInstanceState);

??????? Button? button=(Button)view.findViewById(R.id.item_frgment_bt);

??????? button.setOnClickListener(new View.OnClickListener() { //給抽屜界面的按鈕散設置了一個箭頭

??????????? @Override
??????????? public void onClick(View v) {
??????????????? Toast.makeText (getActivity(),"點擊了按鈕3" ,Toast.LENGTH_SHORT).show();
??????????? }
??????? });
??? }

}

5:Activity

public class MainActivity extends AppCompatActivity {
??? private DrawerLayout mDrawerLayout = null ;
??? @Override
??? protected void onCreate(Bundle savedInstanceState) {
??????? super .onCreate(savedInstanceState);

??????? setContentView(R.layout.activity_main);

??????? FragmentManager fragmentManager=getFragmentManager();
??????? FragmentTransaction ft=fragmentManager.beginTransaction();

??????? DrawerFragment? drawerFragment=new DrawerFragment();

??????? ft.add(R.id.fragment_layout,drawerFragment,"標簽1");//將fragment綁定到已經占有位置的FrameLayout中

??????? ft.commit();

??????? mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

??????? Button button = (Button) findViewById(R.id.btn);
??????? button.setOnClickListener(new View.OnClickListener() {

??????????? @Override
??????????? public void onClick(View v) {
??????????????? // 按鈕按下，將抽屜打開
??????????????? mDrawerLayout.openDrawer(Gravity. LEFT); //從左打開

??????????? }
??????? });
??? }

}
