NavigationView配合Fragment切换+动画+使用+check问题解决方案
令狐新翰
注意在使用Fragment切换动画时要注意fragment是不是v4包
因为v4包跟以后的版本的动画不同具体看：

关于NavigationView的使用：
1.使用xml配置headerLayout 和menu
<android.support.design.widget.NavigationView
android:id="@+id/id_navigationView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/header_just_username"
app:menu="@menu/menu_drawer"
/> header
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="192dp"
android:background="?attr/colorPrimaryDark"
android:orientation="vertical"
android:padding="16dp"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark">
<TextView
android:id="@+id/id_link"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="16dp"
android:text=""/>
<TextView
android:id="@+id/id_username"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@id/id_link"
android:text="菜单"/>
<ImageView
android:layout_width="72dp"
android:layout_height="72dp"
android:layout_above="@id/id_username"
android:layout_marginBottom="16dp"
android:src="@mipmap/ic_launcher"/>
</RelativeLayout> menu
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group >
<item
android:id="@+id/nav_home"
android:icon="@drawable/ic_dashboard"
android:title="常用功能">
<menu>
<item
android:id="@+id/id_detection"
android:icon="@drawable/ic_dashboard"
android:title="@string/detection"
android:checkable="true" />
<item
android:id="@+id/id_calibration"
android:icon="@drawable/ic_event"
android:title="@string/calibration"
android:checkable="true"/>
<item
android:id="@+id/id_manualcalibration"
android:icon="@drawable/ic_headset"
android:title="@string/manualcalibration"
android:checkable="true"/>
<item
android:id="@+id/id_detectionrecord"
android:icon="@drawable/ic_forum"
android:title="@string/detectionrecord"
android:checkable="true"/>
<item
android:id="@+id/id_calibrationrecord"
android:icon="@drawable/ic_headset"
android:title="@string/calibrationrecord"
android:checkable="true"/>
<item
android:id="@+id/id_operatelog"
android:icon="@drawable/ic_forum"
android:title="@string/operatelog"
android:checkable="true"/>
<item
android:id="@+id/id_substancedb"
android:icon="@drawable/ic_event"
android:title="@string/substancedb"
android:checkable="true"/>
</menu>
</item>
<item
android:id="@+id/nav_messages"
android:icon="@drawable/ic_event"
android:title="基本功能">
<menu>
<item
android:id="@+id/id_usermanager"
android:icon="@drawable/ic_forum"
android:title="@string/usermanager"
android:checkable="true"/>
<item
android:id="@+id/id_setup"
android:icon="@drawable/ic_headset"
android:title="@string/setup"
android:checkable="true"/>
</menu>
</item>
</group>
</menu>
点击navigationview时会发现menuItem的check总是出问题于是做了如下修改：
navigationView = (NavigationView) findViewById(R.id.id_navigationView);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
mMenuItemID = menuItem.getItemId();
switch (mMenuItemID) {
case R.id.id_detection:
setTitle(R.string.detection);
if(mainFragment==null)
mainFragment=new MainFragment();
switchContent(mFragment,mainFragment);
break;
case R.id.id_calibration:
setTitle(R.string.calibration);
if(mainFragment==null)
mainFragment=new MainFragment();
switchContent(mFragment, mainFragment);
break;
case R.id.id_manualcalibration:
setTitle(R.string.manualcalibration);
if(mainFragment==null)
mainFragment=new MainFragment();
switchContent(mFragment,mainFragment);
break;
case R.id.id_calibrationrecord:
setTitle(R.string.calibrationrecord);
if(calibrationRecordFragment==null)
calibrationRecordFragment=new CalibrationRecordFragment();
switchContent(mFragment, calibrationRecordFragment);
break;
case R.id.id_detectionrecord:
setTitle(R.string.detectionrecord);
if(detectionRecordFragment==null)
detectionRecordFragment=new DetectionRecordFragment();
switchContent(mFragment,detectionRecordFragment);
break;
case R.id.id_operatelog:
setTitle(R.string.operatelog);
if(operatelogFragment==null)
operatelogFragment=new OperatelogFragment();
switchContent(mFragment,operatelogFragment);
break;
case R.id.id_substancedb:
setTitle(R.string.substancedb);
if(substanceDBFragment==null)
substanceDBFragment=new SubstanceDBFragment();
switchContent(mFragment,substanceDBFragment);
break;
}
//重点在这里
navigationView.getMenu().clear();
navigationView.inflateMenu(R.menu.menu_drawer);
navigationView.getMenu().findItem(mMenuItemID).setChecked(true);
mDrawerLayout.closeDrawer(Gravity.LEFT);
return true;
}
});
public void switchContent(Fragment from, Fragment to) {
if (mFragment != to) {
mFragment = to;
FragmentManager fm = getFragmentManager();
//添加渐隐渐现的动画
FragmentTransaction ft = fm.beginTransaction();
ft.setCustomAnimations( R.animator.fragment_slide_left_enter,
R.animator.fragment_slide_right_exit);
if (!to.isAdded()) { // 先判断是否被add过
ft.hide(from).add(R.id.id_fragmentMain, to).commit(); // 隐藏当前的fragment，add下一个到Activity中
} else {
ft.hide(from).show(to).commit(); // 隐藏当前的fragment，显示下一个
}
}
}
2.可以自定义NavigationView
<android.support.design.widget.NavigationView
android:id="@+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="@layout/nav_header" />
<ListView
android:id="@+id/lst_menu_items"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</android.support.design.widget.NavigationView>
