启动画面应用程序并隐藏操作栏

标签: android user-interface android-actionbar show-hide splash-screen

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);
