Android：以编程方式制作全屏[重复]

Question

我想在点击按钮时全屏显示，并在按下返回按钮时恢复正常。

在 Android 工作室中

Answer 1

在 OnCreate() 中

 Button x = findViewById(R.id.button);
       x.setOnClickListener(new View.OnClickListener() {
          @Override public void onClick(View v) {
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
             WindowManager.LayoutParams.FLAG_FULLSCREEN);
             setContentView(R.layout.mainActivity);
          }
       });

现在您需要退出全屏使用此代码：

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); ActivitiesCurrentContentView.requestLayout();

Answer 2

您可以通过编程方式完成

    public class ActivityName extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // remove title
    Button x = findViewById(R.id.yourButton);
       x.setOnClickListener(new View.OnClickListener() {
          @Override public void onClick(View v) {
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
             WindowManager.LayoutParams.FLAG_FULLSCREEN);
             setContentView(R.layout.main);
          }
       });
}
}
