在项目开发中，

关于android手机横竖屏切换时显示不同的界面，在这里我定义了两个xml布局文件

landscape_screen.xml，portrait_screen.xml

根据屏幕的旋转切换不同的布局文件

重写onConfigurationChanged方法，对其进行监听并判断当前的屏幕状态，根据其状态显示对应的布局文件

当然在manifest.xml中对应的activity中要加上

android:configChanges="keyboardHidden|orientation|screenSize">

贴上代码说话

public classScreenActivity extends Activity implements OnClickListener{

private Button btn;

@Override

protected voidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

//默认为竖屏

setupViewInPortraitLayout();

}

//竖屏界面

private voidsetupViewInPortraitLayout(){

setContentView(R.layout.portrait_screen);

btn = (Button)findViewById(R.id.button1_portrait);

btn.setOnClickListener(this);

}

//横屏界面

private voidsetupViewInLandscapeLayout(){

setContentView(R.layout.landscape_screen);

btn = (Button)findViewById(R.id.button1_landscape);

btn.setOnClickListener(this);

}

@Override

public voidonConfigurationChanged(Configuration newConfig) {

super.onConfigurationChanged(newConfig);

Toast.makeText(ScreenActivity.this,"onConfigurationChanged", Toast.LENGTH_LONG).show();

Configuration cfg =getResources().getConfiguration();

if (cfg.orientation ==Configuration.ORIENTATION_LANDSCAPE) {

setupViewInLandscapeLayout();

} else if(cfg.orientation == Configuration.ORIENTATION_PORTRAIT) {

setupViewInPortraitLayout();

}

}

@Override

public void onClick(Viewarg0) {

// TODO Auto-generatedmethod stub

if(arg0.equals(btn)){

Toast.makeText(ScreenActivity.this,"Click", Toast.LENGTH_LONG).show();

}

}

}
