Question

我开发了自己的Android启动器，它运行得很好，问题是当我点击HOME按钮时它不会将我重定向到HOME页面，我怎么能解决这个问题，谢谢！

这是我的清单文件：

查看Home - 自定义启动器示例。这里有一个关键事件的调度员：

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if (event.getAction() == KeyEvent.ACTION_DOWN) {
            ...
            case KeyEvent.KEYCODE_HOME:
                mHomeDown = true;
                return true;
        }
    } else if (event.getAction() == KeyEvent.ACTION_UP) {
        switch (event.getKeyCode()) {
            ...
            case KeyEvent.KEYCODE_HOME:
                if (!event.isCanceled()) {
                    // Do HOME behavior.
                }
                mHomeDown = true;
                return true;
        }
    }

    return super.dispatchKeyEvent(event);
}

您可以在评论中说明您自己的行为。对于此示例，将hideApplications()调用以隐藏应用程序网格。
