在我的android应用程序中,我有一个抽屉,但是为了获得抽屉,我必须手动单击并拖动该抽屉。如何将符号添加到工具栏? (通过点击我要处理我的抽屉),我还如何使该工具栏在所有其他布局中可见?
这是我的activity_drawer.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawer"
tools:context=".drawer">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:minHeight="?android:attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar" />
<android.support.design.widget.NavigationView
app:headerLayout="@layout/header_drawer"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@color/colorPrimary"
app:itemTextColor="@color/grey"
app:itemIconTint="@color/grey"
app:menu="@menu/menudrawer"
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
这是我的抽屉.java
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.MenuItem;
public class drawer extends AppCompatActivity {
private DrawerLayout mDrawer;
private ActionBarDrawerToggle mToggle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
mDrawer = (DrawerLayout) findViewById(R.id.drawer);
mToggle = new ActionBarDrawerToggle(this,mDrawer,R.string.Open,R.string.Close);
mDrawer.addDrawerListener(mToggle);
mToggle.syncState();
Toolbar toolbar = findViewById(R.id.toolbar);
if (getSupportActionBar()!=null){
setSupportActionBar(toolbar);
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mToggle.onOptionsItemSelected(item))

使用以下代码根据您的需要帮助您
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.str_drawer_o, R.string.str_drawer_clos)
if (getSupportActionBar()!=null)
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.ic_nav_icon, this.getTheme());
actionBarDrawerToggle.setHomeAsUpIndicator(drawable);
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
drawerLayout.closeDrawer(GravityCompat.START);
} else {
drawerLayout.openDrawer(GravityCompat.START);
}
}
});
actionBarDrawerToggle.syncState();
