Android实现布局全屏
本文实例为大家分享了Android实现布局全屏的具体代码,供大家参考,具体内容如下
前言
类似Launcher,希望占用的布局铺满全屏,以调整状态栏及虚拟按键部分的颜色样式。
废话不多说,上案例:
一、效果预览二、案例实现1.新建Android工程2.styles样式增加
values 目录的styles.xml添加如下样式:
<style name='FullTheme' parent='@style/BaseFullTheme'></style><style name='BaseFullTheme' parent='@android:style/Theme.DeviceDefault.Light.NoActionBar'> <item name='android:windowBackground'>@android:color/transparent</item> <item name='android:colorBackgroundCacheHint'>@null</item> <item name='android:windowShowWallpaper'>true</item> <item name='android:windowNoTitle'>true</item></style>
alues-v19 目录的styles.xml添加如下样式:
<style name='FullTheme' parent='@style/BaseFullTheme'> <item name='android:windowTranslucentStatus'>true</item> <item name='android:windowTranslucentNavigation'>true</item></style>
values-v21目录的styles.xml添加如下样式:
<style name='FullTheme' parent='@style/BaseFullTheme'> <item name='android:windowTranslucentStatus'>false</item> <item name='android:windowTranslucentNavigation'>false</item> <item name='android:windowDrawsSystemBarBackgrounds'>true</item> <item name='android:statusBarColor'>#00000000</item> <item name='android:navigationBarColor'>#00000000</item></style>
values-v29目录的styles.xml添加如下样式:
<style name='FullTheme' parent='@style/BaseFullTheme'> <item name='android:colorBackgroundCacheHint'>@null</item> <item name='android:colorEdgeEffect'>#FF757575</item> <item name='android:windowActionBar'>false</item> <item name='android:windowBackground'>@android:color/transparent</item> <item name='android:windowNoTitle'>true</item> <item name='android:windowShowWallpaper'>true</item> <item name='android:windowLayoutInDisplayCutoutMode'>shortEdges</item> <item name='android:enforceStatusBarContrast'>false</item> <item name='android:enforceNavigationBarContrast'>false</item> <item name='android:windowTranslucentStatus'>false</item> <item name='android:windowTranslucentNavigation'>false</item> <item name='android:windowDrawsSystemBarBackgrounds'>true</item> <item name='android:statusBarColor'>#00000000</item> <item name='android:navigationBarColor'>#00000000</item></style>3.布局
layout目录建立activity_main.xml
<?xml version='1.0' encoding='utf-8'?><LinearLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:tools='http://schemas.android.com/tools' android:layout_width='match_parent' android:layout_height='match_parent' android:orientation='vertical' android:background='@android:color/holo_blue_bright'<!-- 测试设置的颜色 --> android:fitsSystemWindows='true' tools:context='.MainActivity'> <Buttonandroid: android:layout_width='wrap_content'android:layout_height='wrap_content'android:text='测试'> </Button></LinearLayout>4.使用
新建MainActivity.java
package com.demo;import android.app.Activity;import android.graphics.Color;import android.os.Build;import android.os.Bundle;import android.view.View;import android.view.Window;import android.view.WindowManager;public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);hideStatusBarNavigationBar();setContentView(R.layout.activity_main); } //关键方法 private void hideStatusBarNavigationBar() {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { Window window = getWindow(); window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE); window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); window.setStatusBarColor(Color.TRANSPARENT); window.setNavigationBarColor(Color.TRANSPARENT); return;}if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { getWindow().addFlags( WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); getWindow().addFlags( WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);} }}
AndroidManifest.xml声明
<?xml version='1.0' encoding='utf-8'?><manifest xmlns:android='http://schemas.android.com/apk/res/android' package='com.demo'> <applicationandroid:allowBackup='true'android:icon='@mipmap/ic_launcher'android:label='@string/app_name'android:roundIcon='@mipmap/ic_launcher_round'android:supportsRtl='true'android:theme='@style/FullTheme'><activity android:name='.MainActivity'> <intent-filter><action android:name='android.intent.action.MAIN' /><category android:name='android.intent.category.LAUNCHER' /> </intent-filter></activity> </application></manifest>
finish
三、填坑:fitsSystemWindows之坑在activity_main.xml中的根布局那增加了android:fitsSystemWindows=“true”,如果不增加这个属性,子view的布局会从最顶上开始,有兴趣的可以修改了试试。
