此代码可能对您有所帮助：

Button buttonSetPortrait = (Button)findViewById(R.id.setPortrait);
Button buttonSetLandscape = (Button)findViewById(R.id.setLandscape);

buttonSetPortrait.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
   }

});

buttonSetLandscape.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
   }

});
