Question

当我点击屏幕上的按钮时，我想关闭我的应用程序。

public WindowManager winManager;
public RelativeLayout wrapperView;
public Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams( WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT);
    this.winManager = ((WindowManager)getApplicationContext().getSystemService(WINDOW_SERVICE));
    this.wrapperView = new RelativeLayout(getBaseContext());
    getWindow().setAttributes(localLayoutParams);
    View.inflate(this, R.layout.activity_main, this.wrapperView);
    this.winManager.addView(this.wrapperView, localLayoutParams);
    button1 = (Button)wrapperView.findViewById(R.id.button1);
    button1.setOnClickListener(mButton1_OnClickListener);
}

View.OnClickListener mButton1_OnClickListener = new View.OnClickListener() {
    public void onClick(final View v){
                winManager.removeView(wrapperView);
                wrapperView.removeAllViews();
                finish();
    }
};

我做了这个活动，但当我点击按钮时，应用程序仍然出现在最近的应用程序菜单上，我不知道为什么。

Answer 1

试试这个：

@Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        finish();
        System.exit(0);
    }

最佳方法是将用户带到Launcher / Home。

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
