Android 实现汉堡菜单后无法在网格视图布局中滚动
我在主活动文件中有一个gridview布局。最初我可以通过滚动查看所有图像，但后来我在同一活动中添加了一个汉堡菜单，gridview图像没有显示所有图像，我也无法滚动。 我在activity.xml文件中添加了scrollview，应用程序不幸停止。 这是logcat：Android 实现汉堡菜单后无法在网格视图布局中滚动,android,android-layout,Android,Android Layout,我在主活动文件中有一个gridview布局。最初我可以通过滚动查看所有图像，但后来我在同一活动中添加了一个汉堡菜单，gridview图像没有显示所有图像，我也无法滚动。 我在activity.xml文件中添加了scrollview，应用程序不幸停止。 这是logcat： 08-01 13:14:05.028 6153-6153/com.example.luke.goweb E/AndroidRuntime: FATAL EXCEPTION: main

有什么帮助吗？或者有什么建议？提前谢谢你。嗯，那不应该发生。尝试将GridView包装为LinearLayout，然后将该LinearLayout放置在ScrollView中。我在滚动视图中的线性布局总是很幸运 编辑：也许你的汉堡包菜单也是部分原因。试试谷歌导航抽屉（文档）的方法，也就是把它们完全放在一个单独的片段中。这样做的好处是允许您在多个活动中使用该菜单，而不必到处复制该XML
编辑2：我刚刚注意到您在框架布局中包含了上述方法中的抽屉布局。在ScrollView中，它肯定会导致崩溃。如果您将它移到ScrollView之外，您的问题应该会消失。嗯，这不应该发生。尝试将GridView包装为LinearLayout，然后将该LinearLayout放置在ScrollView中。我在滚动视图中的线性布局总是很幸运 编辑：也许你的汉堡包菜单也是部分原因。试试谷歌导航抽屉（文档）的方法，也就是把它们完全放在一个单独的片段中。这样做的好处是允许您在多个活动中使用该菜单，而不必到处复制该XML

遵循这些建议中的任何一个，否则这段代码将完成您的工作 如您所述，您可以在网格视图中查看和滚动所有图像。但在实现汉堡菜单或导航抽屉后，卷轴就不起作用了。 我要说的是，不要混淆导航抽屉和网格布局的布局代码，最好将这两个文件分开，并随时调用它。 下面是实现导航抽屉的完整代码。希望这对你有帮助。 首先创建一个xml文件并添加以下代码：
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"

mTitle = mDrawerTitle = getTitle();
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
}

public boolean onPrepareOptionsMenu(Menu menu) {
// If the nav drawer is open, hide action items related to the content view
