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();
}
}
}
