在应用程序运行时禁用Android设备的按钮

Question

我正在开发一个应用程序，当应用程序开始运行时我需要禁用虚拟按钮，因为应用程序中有按钮。任何人都可以帮我解决这个问题吗？提前谢谢。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_1st_main);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

@SuppressWarnings({ "unchecked", "rawtypes" })
private final List hijackKeys = new ArrayList(Arrays.asList(
        KeyEvent.KEYCODE_VOLUME_DOWN, KeyEvent.KEYCODE_VOLUME_UP,
        KeyEvent.KEYCODE_BACK, KeyEvent.KEYCODE_HOME));

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if (hijackKeys.contains(event.getKeyCode())) {
        return true;
    } else {
        return super.dispatchKeyEvent(event);
    }
}

这是最佳解决方案。

public class BaseActivity extends Activity {
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);

            Log.d("Focus debug", "Focus changed !");

        if(!hasFocus) {
            Log.d("Focus debug", "Lost focus !");

            Intent closeDialog = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
            sendBroadcast(closeDialog);
        }
    }

Answer 2

使用以下代码覆盖后退按钮

@Override
public void onBackPressed() {
    // TODO Auto-generated method stub
    //super.onBackPressed();  // nothing to do here
}

现在，对于菜单按钮尝试这样

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
//  getMenuInflater().inflate(R.menu.main, menu);   // comment this line to disable menu button
    return true;
}

禁用菜单按钮的最佳方法是从活动类中删除onCreateOptionsMenu方法...

我真的不知道这是否有效。请试试这个。

将此内容添加到您的主要活动的manifest.xml中：

<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.HOME" />

试试这种方式

@Override
public void onAttachedToWindow() {
    //only desable home button
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}
