新建一个项目DrawerlayoutDemo,抽屉控件,这里使用官方自带的控件Drawerlayout来实现,这个控件只能是根控件,然后他抽屉部分和主界面是用layout_gravity来区别.
activity_main.xml代码:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawerlayout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content"> <Button android:id="@+id/button" android:text="打开抽屉" android:layout_height="wrap_content" android:layout_width="wrap_content"></Button> </LinearLayout> </LinearLayout> <LinearLayout android:layout_width="270.dip" android:layout_gravity="start" android:layout_height="match_parent" android:background="@color/colorPrimaryDark" android:orientation="vertical"> <TextView android:text="这是左边栏~" android:layout_height="wrap_content" android:layout_width="wrap_content"/> </LinearLayout> </android.support.v4.widget.DrawerLayout>MainActivity.java代码: package com.example.administrator.drawerlayoutdemo; import android.app.Activity; import android.support.v4.widget.DrawerLayout; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Gravity; import android.view.View; import android.widget.Button; public class MainActivity extends Activity { private DrawerLayout drawerLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); drawerLayout =(DrawerLayout)findViewById(R.id.drawerlayout); ((Button)findViewById(R.id.button)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { drawerLayout.openDrawer(Gravity.LEFT); } }); } } 看一下效果:第一张是打开之后的效果,第二张是没打开的效果,当然了,用手向右边滑动也是可以的~
