Android 如何使用NavigationView浏览活动?
有没有一种方法可以让我创建一个Android 如何使用NavigationView浏览活动?,android,Android,有没有一种方法可以让我创建一个NavigationView(及其元素)并调用其他自定义活动,同时为所有这些活动维护相同的NavigationView 我按照@johnrao07所说的做了,并创建了一个活动,它将作为我所有活动的基本活动。看起来是这样的: public class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { HealthFil
NavigationView
(及其元素)并调用其他自定义活动,同时为所有这些活动维护相同的NavigationView
我按照@johnrao07所说的做了,并创建了一个活动
,它将作为我所有活动的基本活动
。看起来是这样的:
public class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
HealthFileSQLiteOpenHelper healthFileHelper;
SQLiteDatabase db;
DrawerLayout drawerLayout;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// Handle navigation view item clicks here.
int id = menuItem.getItemId();
if (id == R.id.nav_home) {
// Handle the camera action
finish();
} else if (id == R.id.nav_log_out) {
finish();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.CoordinatorLayout 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:fitsSystemWindows="true"
tools:context="com.example.testnavigation2.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!-- <include layout="@layout/profiles_content" /> -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Put what you want as your normal screen in here, you can also choose for a linear layout or any other layout, whatever you prefer -->
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
android:background="@android:color/white"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
然后我有一个自定义的活动
,我希望它从基本活动
扩展:
public class ProfilesActivity extends BaseActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// TROUBLE HERE
setContentView(R.layout.profiles_content);
}
我希望这个活动
有自己的内容,并且我希望导航视图
显示在从BaseActivity扩展而来的任何活动中
没有运气
这是我的xml:

但我仍然无法在每个活动中看到NavigationView(使用此方法,我的屏幕上完全丢失了它)
你知道我做错了什么吗?你的所有其他活动都应该扩展MainActivity,它包含
应用程序bar\u main.xml
文件中的导航视图,而且,您必须对所有希望使用NavigationView
的活动布局执行相同的操作。你的app\u bar\u main.xml
应该是这样的:
public class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
HealthFileSQLiteOpenHelper healthFileHelper;
SQLiteDatabase db;
DrawerLayout drawerLayout;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// Handle navigation view item clicks here.
int id = menuItem.getItemId();
if (id == R.id.nav_home) {
// Handle the camera action
finish();
} else if (id == R.id.nav_log_out) {
finish();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}

不工作。。。如果我扩展MainActivity,它不会保留NavigationView和其他任何东西,好的,我想它现在起作用了。我相信这是可行的。谢谢
