Question

我正在使用抽屉布局，里面有一个ListView和RelativeLayout，用于我的应用程序上的汉堡包菜单。单击ListView上的项目时，我想要更改为新活动。但是，当我单击ListView上的项目时，没有任何事情发生。我的代码：

activity_main.xml中：

Answer 1

在bigevilbrain

之后添加此行

addDrawerItems();

Answer 2

通过添加

修复

mDrawerList.bringToFront();
mDrawerLayout.requestLayout();

到

public void onDrawerOpened(View drawerView)

Answer 3

我在OnItemClick方法中看不到任何开始新活动的声明。您只是获得string并在同一活动中制作Toast。尝试点击id点击Item，然后根据Activity开始id。

这里有一些代码供您使用。

mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Intent intent = new Intent(currentActivity.this, parent.class);
            startActivity(intent);
        }
    });
}

如果此代码能够让您的应用运行，请告诉我们。并且接受了这个答案。
