android DrawerLayout侧滑菜单实现

在网上看到很多实现侧滑菜单的例子，但是都比较麻烦。 也找了一个比较简单的实现，用到DrawerLayout。只需要在xml文件中配置好，在Activity中就可以直接使用了。

xml文件如下

<RelativeLayout 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.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<!-- The main content view -->

<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >

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

<TextView
android:id="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>

<!-- The left drawer -->

<ListView
android:id="@+id/left_list"
android:layout_width="150dp"
android:layout_height="match_parent"
android:background="#ffffff"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>

</RelativeLayout>

Activity如下

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.TextView;

public class Main extends Activity {
private DrawerLayout mDrawerLayout;
private ListView left_list;
private TextView text;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
left_list = (ListView)this.findViewById(R.id.left_list);
text = (TextView)this.findViewById(R.id.text);
List<String> list = new ArrayList<String>();
list.add("abcedfg");
list.add("hijklmn");
list.add("opqrst");
list.add("uvwxyz");
left_list.setAdapter(new ArrayAdapter<>(left_list.getContext(), android.R.layout.simple_list_item_1, list));
left_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
text.setText("hello" + arg2);
System.out.println("hello");
}
});
Button button = (Button) findViewById(R.id.btn);
button.setOnClickListener(new OnClickListener()
{

@Override
public void onClick(View v)
{
mDrawerLayout.openDrawer(Gravity.LEFT);
}
});
}
}

这样，就能很简单的实现侧滑菜单的效果了。
