横竖屏切换显示不同布局

在项目开发中，

成都网站建设、网站制作的关注点不是能为您做些什么网站，而是怎么做网站，有没有做好网站，给创新互联建站一个展示的机会来证明自己，这并不会花费您太多时间，或许会给您带来新的灵感和惊喜。面向用户友好，注重用户体验，一切以用户为中心。

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();

}

}

}
