Android 中隐藏虚拟按键的方法实例代码

下面通过一段代码给大家讲解android 隐藏虚拟按键的方法，废话不多说了，大家多多看看代码和注释吧，具体代码如下所示：

 
  protected void hideBottomUIMenu() {
    //隐藏虚拟按键，并且全屏
    if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
      View v = this.getWindow().getDecorView();
      v.setSystemUiVisibility(View.GONE);
    } else if (Build.VERSION.SDK_INT >= 19) {
      //for new api versions.
      View decorView = getWindow().getDecorView();
      int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
          | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;
      decorView.setSystemUiVisibility(uiOptions);
    }
  }

//隐藏虚拟按键，并且全屏
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN);
    getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
      @Override
      public void onSystemUiVisibilityChange(int visibility) {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN);
      }
    });

例子

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
public class HideTestActivity extends Activity implements OnClickListener{ 
  View main ; 
   
  @Override 
  public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    main = getLayoutInflater().from(this).inflate(R.layout.main, null); 
    main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); 
    main.setOnClickListener(this); 
    setContentView(main); 
  } 
  @Override 
  public void onClick(View v) { 
    int i = main.getSystemUiVisibility(); 
    if (i == View.SYSTEM_UI_FLAG_HIDE_NAVIGATION) { 
      main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); 
    } else if (i == View.SYSTEM_UI_FLAG_VISIBLE){ 
      main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE); 
    } else if (i == View.SYSTEM_UI_FLAG_LOW_PROFILE) { 
      main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); 
    } 
  } 
}
