[英]How to place tabs at bottom of app in a tabbedactivity
我正在嘗試使用android中的tabbedActivity創建一個簡單的應用程序。 我想將選項卡放在屏幕底部。
這是用android studio創建我的Activity時得到的。
我想要的是屏幕底部的“ SECTION 1 SECTION 2 SECTION 3”部分。
這是我的xml文件:
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
此代碼包裝在CoordinatorLayout
。 問題是,如果我采用TabLayout
並將其放在viewPager之后,則會從屏幕上刪除它。
有人知道嗎?
編輯:感謝@Vivek Mishra的答案,它有效! 謝謝
您可以像下面這樣使用tabhost在底部設置標簽,
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabHost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"></TabWidget>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="50dp">
<LinearLayout
android:id="@+id/tab1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffc916"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="This is tab 1" />
</LinearLayout>
<LinearLayout
android:id="@+id/tab2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#da8200"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="This is tab 2" />
</LinearLayout>
<LinearLayout
android:id="@+id/tab3"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#5b89ff"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="This is tab 3" />
</LinearLayout>
</FrameLayout>
</RelativeLayout>
</TabHost>
MainActivity.java
public class MainActivity extends AppCompatActivity {
TabHost tabHost;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost host = (TabHost) findViewById(R.id.tabHost);
host.setup();
//Tab 1
TabHost.TabSpec spec = host.newTabSpec("Tab One");
spec.setContent(R.id.tab1);
spec.setIndicator("Tab One");
host.addTab(spec);
//Tab 2
spec = host.newTabSpec("Tab Two");
spec.setContent(R.id.tab2);
spec.setIndicator("Tab Two");
host.addTab(spec);
//Tab 3
spec = host.newTabSpec("Tab Three");
spec.setContent(R.id.tab3);
spec.setIndicator("Tab Three");
host.addTab(spec);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
您必須在AppBarLayout之外添加TabLayout下面的代碼對我有用
<?xml version="1.0" encoding="utf-8"?>
<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:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="project.annadata.HomeActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<android.support.design.widget.TabLayout
android:id="@+id/tabs2"
android:layout_width="match_parent"
android:layout_gravity="end|bottom"
android:layout_height="wrap_content" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_marginRight="20dp"
android:layout_marginBottom="50dp"
app:srcCompat="@android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
嘗試在XML中添加`android:layout_alignParentBottom =“ true”屬性
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" />
