如何将导航抽屉添加到我现有的代码中？
我有一个应用程序，其中我有一个导航面板，其中包含我想要应用导航抽屉的菜单按钮，目前它占用了整个屏幕，但我想通过应用导航抽屉将其限制为屏幕的3/4 ，但我从来没有碰过导航抽屉之前，所以没有线索，任何帮助或指导将是伟大的。也通过一些文件，并得到困惑:(这是我的代码：
这里是我的导航面板布局类：

这是添加导航抽屉的好文章：http://developer.android.com/training/implementing-navigation/nav-drawer.html
您的导航抽屉显示一个空白面板，因为您的activity_main.xml中的抽屉视图是一个ListView（您尚未设置任何数据）。
你想让这个视图成为你的片段。
你的activity_main.xml文件应该看起来像。 确保将片段标记中的类替换为正确的导航片段类。
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

请注意，导航抽屉的状态由抽屉布局管理。 DrawerLayout和抽屉碎片绑定在onCreate方法中。
如果遇到麻烦，请参阅我提到的文章。
---编辑----
以下是我在应用中使用的一项活动。 它显示了如何添加抽屉切换（我发布的链接也显示了这一点）。
你应该能够将它与你当前的活动合并，并有一个工作的导航抽屉。
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);
}
}
