我正在试图弄清楚如何隐藏动态栏以进行初始屏幕活动。 我做了一些在我的启动画面上隐藏我的操作栏的东西,但有一个问题: 在我的启动画面出现之前,有一个活动,其中有一个动作栏短暂出现......我不知道如何隐藏它!
我的启动画面仅在我们第一次触摸应用程序时出现,就像介绍应用程序一样。
代码:
package com.example.basicmaponline;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Window;
public class Intro extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
getActionBar().hide();
setContentView(R.layout.intro);
Thread timer = new Thread(){
public void run(){
try{
sleep(3000);
}catch (InterruptedException e) {
e.printStackTrace();
}finally{
Intent openMenu = new Intent("com.example.basicmaponline.MENU");
startActivity(openMenu);
}
}
};
timer.start();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}

为什么不在清单中添加第一个活动的主题来排除操作栏,甚至可能是通知栏?
类似的东西:
<application
android:allowBackup="true"
android:icon="@drawable/lojacidadao"
android:label="@string/app_name"
android:theme="@style/AppTheme">
<activity
android:name="com.example.basicmaponline.Intro"
android:screenOrientation="portrait"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
...
如果你扩展普通的Activity
类,这应该有效。
如果您的活动扩展AppCompatActivity
,请使用此主题,例如:
<style name="AppTheme.Splash" parent="@style/Theme.AppCompat.NoActionBar">
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
意思是:
<activity ...
android:theme="@style/AppTheme.Splash" >
...
顺便说一句,你有动作栏的原因是因为你已经在应用程序标签中设置了默认主题,因此它不是你之前的活动,它实际上是你自己的启动活动。

如果您的构建目标是sdk 5.0或更高版本(AppTheme样式是Theme.AppCompat.Light.DarkActionBar。)
<activity
android:name=".Splash"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat.Light.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

你有问题是这些行
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
getActionBar().hide();
不需要它们,因为根本不应该调用ActionBar
,启动画面不使用它,并且应该是完全独立的Activity
。
您需要两个Activities
。一个用于Splash Screen,它有自己的布局。第二个是主Activity
,可以是登录屏幕或欢迎屏幕等。
启动画面类应如下所示
public class SplashScreen extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.yourlayoutfile);
Thread loading = new Thread() {
public void run() {
try {
sleep(5000);
Intent main = new Intent(SplashScreen.this, Main.class);
startActivity(main);
}
catch (Exception e) {
e.printStackTrace();
}
finally {
finish();
}
}
};
loading.start();
}
}
XML文件
<?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:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"
tools:context=".SplashScreen" >
// if not using an image replace with whatever is to be shown on the splash screen
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/logo" />
</LinearLayout>
现在第二个Activity
的布局包含ActionBar
等。
答案 3 :(得分:0)
//add to AndroidManifest for SplashScreen
<activity
android:name="<YOUR_PACKAGENAME.ACTIVITY>"
android:theme="@style/AppTheme.NoActionBar"
.........../>
//add this styles to styles.xml
<style name="AppTheme.NoActionBar">
<item name="android:background">@android:color/transparent</item>
<item name="android:windowDisablePreview">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@null</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
//add this code to Activity
public class SplashScreen extends AppCompatActivity {
.
.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
.
.
.
}
}

又甜又甜,
在OnCreate上执行
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
