DrawerLayout - 學會使用
NavigationView
- 學會使用ToolBar+DrawerLayout+NavigationView實現側滑抽屜效果
- 學會實現Toolbar在頂部以及Toolbar被遮擋的兩種效果
效果展示
側滑控制項我們在開發的過程中經常用到,廢話不多說,先上圖:
實現過程
如果要實現上圖的展示效果,需要先創建個BaseActivit類,這個類裡面包含Toolbar的初始化,然後再創建DrawerLayout相關的Activity
創建BaseActivity及相關XML文件
activity_base.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
app:contentInsetStartWithNavigation="0dp"
android:theme="@style/ToolBarStyle"
app:titleTextColor="@color/white">
</android.support.v7.widget.Toolbar>
<FrameLayout
android:id="@+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</LinearLayout>
</LinearLayout> BaseActivity
package com.vv.drawerlayout.ui.base;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.FrameLayout;
import com.vv.drawerlayout.R;

public abstract class BaseActivity extends AppCompatActivity {
protected Toolbar mToolbar;
protected FrameLayout mContainerLayout;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
mToolbar = findViewById(R.id.toolbar);
mContainerLayout = findViewById(R.id.frameLayout);
boolean isToobar = initToolbar();
if (isToobar) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onNavigationClick();
}
});
} else {
mToolbar.setVisibility(View.GONE);
}
initContent(getLayoutId());
}
private void initContent(int layoutId) {
if (layoutId != 0) {
View contentView = LayoutInflater.from(this).inflate(layoutId, mContainerLayout, false);
mContainerLayout.addView(contentView);
ButterKnife.bind(this);
initViews();
}
}
/**

protected abstract int getLayoutId();
private void onNavigationClick() {
finish();
}
/**

*/
protected abstract boolean initToolbar();
}
創建DrawerLayout相關的Activity以及相關的XML文件
activity_main.xml
<?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=".ui.MainActivity">
<android.support.design.widget.NavigationView

</LinearLayout>navigation_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

</menu>- 如果使用Toolbar,那麼需要把系統的主題換成沒有ActionBar的主題,修改
style.xml文件
<resources>
<!-- Base application theme. -->
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme" parent="AppTheme.Base"></style>
<style name="ToolBarStyle" parent="@style/BaseToolBarStyle"></style>
</resources>
MainActivity實現
package com.vv.drawerlayout.ui;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.view.MenuItem;
import com.vv.drawerlayout.R;
import com.vv.drawerlayout.ui.base.BaseActivity;
import butterknife.Bind;
/**
* @author ShenZhenWei
*/
public class MainActivity extends BaseActivity {
@Bind(R.id.navigation_view)
NavigationView mNavigationView;
@Bind(R.id.drawer_layout)
DrawerLayout mDrawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBarDrawerToggle mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,mToolbar,
R.string.navigation_drawer_open,
R.string.navigation_drawer_close);
mToggle.syncState();
mDrawerLayout.addDrawerListener(mToggle);
mNavigationView.setItemIconTintList(null);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
return false;
}
});
}
@Override
protected void initViews() {
}
@Override
protected int getLayoutId() {
return R.layout.activity_main;
}
@Override
protected boolean initToolbar() {
mToolbar.setTitle(R.string.home);
mToolbar.setNavigationIcon(R.drawable.ic_menu_black_24dp);
return true;
}
}
- 運行查看效果
優化
但是現在我們發現側邊欄是沒有選中狀態的,如效果圖所示,
我們怎麼才能是左邊的導航欄有選擇狀態呢?
給左邊的導航欄加上選中效果
- 首先在佈局文件中,
NavigationView的控制項的meun中註明一個behavior
<group
android:checkableBehavior="single">
<item
android:title="@string/home">
</item>
</group> android:checkableBehavior="single"表示每一項都是單選,如果不標明的話,NavigationView不會有選中效果.
- 在Java文件中增加監聽器
mNavigationView.setNavigationItemSelectedListener(onNavigationItemSelectedListener);NavigationView.OnNavigationItemSelectedListener onNavigationItemSelectedListener = new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_favorite_article:
break;
case R.id.menu_about:
break;
case R.id.menu_exit:
break;
case R.id.menu_home:
break;
default:
break;
}
//關閉側邊欄
mDrawerLayout.closeDrawers();
return true;
}
};- 運行效果
改變圖標的顏色
我們給剛剛增加的NavigationView的控制項的meun的Item增加一個icon
<group
android:checkableBehavior="single">
<item
android:id="@+id/menu_home"
android:icon="@mipmap/ic_launcher"
android:title="@string/home">
</item>
</group>ok看下現在的效果:
5我們發現首頁 旁邊的圖標變成了黑色.這並不是我們想要的.
我們怎麼去更改Icon的顏色呢,有兩種方法:
- 在NavigationView的佈局xml文件里增加
app:itemIconTint="@color/xxx"屬性,可以設置Icon的圖片顏色為統一的一種顏色
activity_main.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:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.MainActivity">
<android.support.design.widget.NavigationView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/navigation_view"
android:layout_gravity="left|start"
app:headerLayout="@layout/header_layout"
app:menu="@menu/navigation_menu"
app:itemIconTint="@color/_0091ea">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>運行效果如下:
我們可以看到所有的Icon的圖片顏色全部換成了統一的藍色.但是首頁旁邊的Icon仍不是我們想要的圖標顏色.這就得需要第二種方法了.
- 我們如果想讓Icon顯示本省的顏色,就得在java文件裡面調用以下方法:
mNavigationView.setItemIconTintList(null);MainActivity
package com.vv.drawerlayout.ui;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;

import com.vv.drawerlayout.ui.base.BaseActivity;
import butterknife.Bind;
/**

public class MainActivity extends BaseActivity {
@Bind(R.id.navigation_view)
NavigationView mNavigationView;
@Bind(R.id.drawer_layout)
DrawerLayout mDrawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBarDrawerToggle mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,mToolbar,
R.string.navigation_drawer_open,
R.string.navigation_drawer_close);
mToggle.syncState();
mDrawerLayout.addDrawerListener(mToggle);
mNavigationView.setItemIconTintList(null);
mNavigationView.setNavigationItemSelectedListener(onNavigationItemSelectedListener);
}
@Override
protected void initViews() {
}
@Override
protected int getLayoutId() {
return R.layout.activity_main;
}
@Override
protected boolean initToolbar() {
mToolbar.setTitle(R.string.home);
mToolbar.setNavigationIcon(R.drawable.ic_menu_black_24dp);
return true;
}
NavigationView.OnNavigationItemSelectedListener onNavigationItemSelectedListener = new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_favorite_article:
break;
case R.id.menu_about:
break;
case R.id.menu_exit:
break;
case R.id.menu_home:
break;
default:
break;
}
//關閉側邊欄
mDrawerLayout.closeDrawers();
return true;
}
};
}
運行效果:
可以看到,這個效果就是我們想要的~
改變Item的背景,改變Item的TextColor
- 如果要改變Item的背景,我們需要用到
NavigationView的.app:itemBackground=""方法 - 如果要改變Item的TextColor,我們需要用到
NavigationView的app:itemTextColor=""方法

app:itemIconTint="@color/_0091ea">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>效果如下:
給Item之間增加分割線
我們只需要在以上基礎上增加一個group_id即可.即:講menu先放入到group組中,然後再給這個group賦上id的值,就能實現分割線效果.

怎麼實現Toolbar被遮擋的側滑抽屜效果
我們常見的應用,像網易雲音樂,QQ等都是Toolbar被遮擋的側滑效果.
我們實現這種效果就得讓DrawerLayout包含在Toolbar外面
