[英]Open Navigation Drawer by button
I tried to called navigation drawer from my activity, but nothing happened.Should I used ActionBarDrawerToggle? 我尝试从活动中调用导航抽屉,但没有任何反应。我应该使用ActionBarDrawerToggle吗?
public class SettingsDrawer {
Context mContext;
ArrayList<SettingsDrawerItem> items;
ListView listView;
ImageView logo;
DrawerLayout mDrawerLayout;
public SettingsDrawer(Context context) {
this.mContext = context;
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.settings_drawer_layout, null);
mDrawerLayout = (DrawerLayout) view.findViewById(R.id.drawerLayout);
listView = (ListView) view.findViewById(R.id.settingsList);
logo = (ImageView) view.findViewById(R.id.logo);
DrawListAdapter adapter = new DrawListAdapter(mContext, items);
listView.setAdapter(adapter);
mDrawerLayout.openDrawer(Gravity.LEFT);
}
And in my activity 在我的活动中
public class Activity extends AppCompatActivity{
Button settingsDrawerButton =(Button)findViewById(R.id.settingsDrawer);
settingsDrawerButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(TAG,"settings drawer click!");
SettingsDrawer s = new SettingsDrawer(Activity.this);
}
});
}
UPDATE: XML I tried to set up like that: mDrawerLayout.openDrawer(drawerPane) but Ive got classCastException as well. 更新:XML我试图像这样设置:mDrawerLayout.openDrawer(drawerPane)但我也得到了classCastException。 I thought it was quite understable because the DrawerLayout cannot casts to RelativeLayout.
我认为这很不稳定,因为DrawerLayout无法转换为RelativeLayout。
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="280dp"
android:layout_height="match_parent"
android:id="@+id/drawerPane"
android:layout_gravity="start">
<RelativeLayout
android:id="@+id/logoBox"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="@color/material_blue_grey_800"
android:padding="8dp" >
<ImageView
android:id="@+id/logo"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginTop="15dp"
android:layout_centerInParent="true"/>
</RelativeLayout>
<ListView
android:id="@+id/settingsList"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_below="@+id/logoBox"
android:choiceMode="singleChoice"
android:background="#ffffffff" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
Find the drawer layout like this: 找到这样的抽屉布局:
myDrawerLayout = (DrawerLayout) getView().findViewById(R.id.yourdrawer);
The variable myDrawerLayout
should be field in your activity: 变量
myDrawerLayout
应该是您的活动中的字段:
DrawerLayout myDrawerLayout;
Then its Better to make a method like this in your activity: 然后最好在您的活动中创建这样的方法:
public void openDrawer(){
myDrawerLayout.openDrawer(mDrawerLayout);
} }
Then easily call this method whever you want to close the drawer ;) 然后,只要您要关闭抽屉,就可以轻松调用此方法;)
mDrawerLayout.openDrawer(listView);
the below code is my xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="mActivity">
<android.support.v4.widget.DrawerLayout
android:id="@+id/mDrawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:id="@+id/mDrawerMainLayout"
android:layout_width="340dp"
android:layout_gravity="start"
android:layout_height="match_parent">
<ListView
android:id="@+id/mListView"
android:layout_width="340dp"
android:layout_height="match_parent"
android:background="@color/white"
android:choiceMode="singleChoice"
android:dividerHeight="1dp" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout> `from that I fixed private void`
openAndColseDrawerList() {
if (mDrawerLayout.isDrawerOpen(Gravity.LEFT)) {
mDrawerLayout.closeDrawer(mDrawerMainLayout);
} else
mDrawerLayout.openDrawer(mDrawerMainLayout);
}
