[英]How to make a tabbed activity go full screen in Android?
I am trying to make a tabbed activity(with swipe pages) go full screen but its not working....I have tried the way I know to resolve the issue ie using, 我正在尝试使带选项卡的活动(带有滑动页面)全屏显示,但无法正常工作。...我尝试了我所知道的解决问题的方式,即使用,
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
but this crashes my app.... Can anyone walk me through for this, please ? 但这种崩溃我的应用程序.... 谁能走我通过这一点,好吗 ? PS I have used fragments to make individual swipe pages.
PS我使用片段制作单个的滑动页面。
Here is the Java file for the Activity 这是活动的Java文件
package com.example.neo.introv21;
import android.app.Activity;
import android.content.Intent;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

import android.view.WindowManager;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
/**
* The {@link android.support.v4.view.PagerAdapter} that will provide
* fragments for each of the sections. We use a
* {@link FragmentPagerAdapter} derivative, which will keep every
* loaded fragment in memory. If this becomes too memory intensive, it
* may be best to switch to a
* {@link android.support.v4.app.FragmentStatePagerAdapter}.
*/
private SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {@link ViewPager} that will host the section contents.
*/
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//No title bar is set for the activity
requestWindowFeature(Window.FEATURE_NO_TITLE);
//Full screen is set for the Window
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
//This is to hide the toolbar that resides on the top of the screen instead
//of using the fullscreen activity
//Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// setSupportActionBar(toolbar);
// getSupportActionBar().hide();
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
/*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();
}
});*/
}
@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);
}
/**
* A {@link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the sections/tabs/pages.
*/
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position){
case 0:
page1 pg1_object = new page1();
return pg1_object;
case 1:
page2 pg2_object = new page2();
return pg2_object;
case 2:
page3 pg3_object = new page3();
return pg3_object;
case 3:
page4 pg4_object = new page4();
return pg4_object;
case 4:
page5 pg5_object = new page5();
return pg5_object;
case 5:
page6 pg6_object = new page6();
return pg6_object;
case 6:
page7 pg7_object = new page7();
return pg7_object;
case 7:
page8 pg8_object = new page8();
return pg8_object;
case 8:
page9 pg9_object = new page9();
return pg9_object;
default:
return null;
}
}
@Override
public int getCount() {
// Show 9 total pages.
return 10;
}
}
This is one of the java file that acts like a fragment to inflate the tabbed activity 这是一个Java文件,它的作用就像一个片段,用来扩展选项卡式活动
public class page1 extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.page1, container, false);
return rootView;
}
}
Supporting XML file for the fragment page 片段页面的支持XML文件
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.example.neo.introv21.MainActivity">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ss1"
tools:ignore="ContentDescription" />
</android.support.constraint.ConstraintLayout>
To make any activity go full screen just follow this - 1. Add this theme to styles.xml 要使所有活动全屏显示,只需遵循以下步骤:1.将主题添加到styles.xml
<style name="AppTheme.NoTitle" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
2. Apply this theme to your activity in manifest 2.将此主题应用于清单中的活动
<activity android:name=".YourActivity"
android:theme="@style/AppTheme.NoTitle"/>
3. Override onWindowsFocusChanged in your activity 3.覆盖活动中的onWindowsFocusChanged
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus)
if (Build.VERSION.SDK_INT >= 19) {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
} else {
if (Build.VERSION.SDK_INT > 10) {
findViewById(android.R.id.content).setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
}
}
}
PS - If you want action bar for your app do not set below in your theme. PS-如果您想要应用程序的操作栏,请不要在主题下方设置。
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
