我有一个应用程序,其中有一个带菜单按钮的导航面板,我想在上面应用抽屉导航,目前它占据了整个屏幕,但我想通过应用导航将其限制在屏幕的 3/4它上面的抽屉,但我之前从未接触过抽屉导航,所以不知道,任何帮助或指导都会很棒。还浏览了一些文档并感到困惑:(这是我的代码:

这是我的导航面板布局类:

最佳答案

这是一篇添加抽屉导航的好文章:http://developer.android.com/training/implementing-navigation/nav-drawer.html

您的抽屉导航显示一个空白面板,因为您的 activity_main.xml 中的抽屉 View 是一个 ListView(您尚未为其设置任何数据)。

您想使这个 View 成为您的 fragment 。

您的 activity_main.xml 文件应该如下所示。确保将 fragment 标记上的类替换为导航 fragment 的正确类。

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<!-- This fragment container is your the place to put your activities content -->

<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/altercolor2" />

<!--
This is your navigation drawer. You can adjust the width here, but it should
be between 240dp and 320dp
-->

<fragment
android:id="@+id/drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
class="com.yourapp.NavigationPanelFragment" />

</android.support.v4.widget.DrawerLayout>

您的 MainActivity 应该看起来像这样:

public class MainActivity extends AbsBaseaActivity implements OnBackStackChangedListener {
public static final int REQUEST_CODE_LIST = 100;

private Fragment mDrawer;
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;

public boolean isNavigationOpen() {

请注意,抽屉导航的状态由抽屉布局管理。 DrawerLayout 和抽屉 fragment 在 onCreate 方法中绑定(bind)。

如果遇到麻烦,请参阅我提到的文章。

--- 编辑 ----

下面是我在应用程序中使用的 Activity 。它显示了如何添加抽屉开关(我发布的链接也显示了这一点)。

您应该能够将其与您当前的 Activity 合并,并拥有一个可用的抽屉导航。

public class SampleActivity extends AbsBaseaActivity {

private Fragment mDrawer;
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;

@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerMenuItems = getResources().getStringArray(R.array.home_menu_drawer_titles);
mDrawer = (fragment) findViewById(R.id.drawer);

/* Set up the drawer toggle */
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_closed) {

/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
getActionBar().setTitle(R.string.activity_title);
}

/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(R.string.app_name);
}
};

// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);

}

/**
* Backward-compatible version of {@link ActionBar#getThemedContext()} that
* simply returns the {@link android.app.Activity} if <code>getThemedContext</code> is unavailable.
*/
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH) private Context getActionBarThemedContextCompat() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
return getActionBar().getThemedContext();
} else {
return this;
}
}

@Override protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
mDrawer.setItemChecked(0, true);
}

@Override public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}

@Override public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if (mDrawerLayout.isDrawerOpen(mDrawer)) {
mDrawerLayout.closeDrawer(mDrawer);
} else {
mDrawerLayout.openDrawer(mDrawer);
}
return true;
}
return super.onOptionsItemSelected(item);
}
}

如果您遇到错误,请发布错误内容。
