所有活动中的导航抽屉和操作栏？
[英]Navigation Drawer and action bar in all activity?
问题描述
我已经通过扩展基本活动在所有活动上实现了操作栏和导航抽屉，但是当我在子活动中使用setcontent视图时，导航抽屉无法解决该问题！ 这是我的代码：
MainActivity包含导航抽屉：

我试图在子活动中填充listview我可以获取listview但导航抽屉缺少如何解决此问题的方法！

为此，您可以使用XML文件中的View Stub ，这对于所有Java文件都是通用的。 意味着您应该制作一个单独的XML（即，将所有xml文件的通用代码写入该文件），并以不同的java文件（活动文件）访问该XML文件。 您可以从下面的代码行中更好地理解。 在您的主/公用XML文件中添加以下内容，其中包含带有View Stub的导航抽屉和操作栏。
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/Home"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:showIn="@layout/activity_home"
tools:context="com.example.bhuvneshgautam.cityretails.HomeActivity">
<ViewStub
android:id="@+id/layout_stub"
android:inflatedId="@+id/message_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.75" />
</RelativeLayout>
现在在创建时在每个Java文件（活动Java文件）中添加以下代码行
ViewStub stub = (ViewStub) findViewById(R.id.layout_stub);
stub.setLayoutResource(R.layout.home_content);
View inflated = stub.inflate();
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
现在使用“ R.layout.home_content”传递到XML文件名，该文件名包含要在不同页面中不同的代码。以下是我项目的一个文件代码，其中包含要在该文件中不同的代码。 在home_content.xml中
<ImageView
android:id="@+id/Hpersonalcare"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/personalcare"
android:scaleType="centerCrop"/>

你必须使用View Stub
<ViewStub
android:id="@+id/layout_stub"
android:inflatedId="@+id/message_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.75" />
在您的MainActivity中...
Main2Activity.java
public class HomeActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
.........................
@Override
protected void onCreate(Bundle savedInstanceState) {
.....................
ViewStub stub = (ViewStub) findViewById(R.id.lay_stub);
stub.setLayoutResource(R.layout.home_content);
View inflated = stub.inflate();
Toolbar toolbar = (Toolbar) findViewById(R.id.tlbar);
setSupportActionBar(tlbar);
FloatingActionButton fab = (FloatingActionButton)findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();

不要再次使用setContentView(...) ，它会在Main2Activity移除抽屉中覆盖此调用。 让您的“主” Activity为抽象并创建protected abstract int getCustomContentView(...) ，它将在所有扩展的Activities中都可用，返回您当前在setContentView内部传递的id并将其在父对象中充气并添加到Drawer的容器中。 它可能在OnCreate中完成，所以在超级之后，您可以在childs中的findViewById之后直接调用
public abstract class Main2Activity extends Activity {
protected abstract int getCustomContentViewResId();
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
LinearLayout container = (LinearLayout) findViewById(R.id.drawer_container);
int layoutResourceId = getCustomContentView();
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View innerView = inflater.inflate(layoutResourceId , container, true);
//rest of code
}
}
铅：
public class LeadActivity extends Main2Activity {
protected int getCustomContentViewResId(){
return R.layout.activity_lead;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_lead);
// this goes to getCustomContentViewResId
ListView lv = (ListView)findViewById(R.id.listView);
// inflating already done in super.onCreate by extended Main2Activity so you may call findViewById directly without setContentView
}
//rest of code
}
带导航抽屉的操作栏
