Splash Screen will not display

2019-07-20 06:35发布

I am trying to implement a Splash Screen using this java and xml code. I created a separate java class from my main activity and placed the java code inside. I created an xml layout in my layout file and placed the xml code inside. However, my app appears normally without a splash screen. It never shows, but the app does not have any errors. Eclipse is not showing any errors either. What could be the cause to this? Thank you in advance. Here is the code.

Java:

package com.carouseldemo.main;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Menu;

public class Splash extends Activity {

    private final int SPLASH_DISPLAY_LENGHT = 1000;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.splash);

        /* New Handler to start the Menu-Activity 
         * and close this Splash-Screen after some seconds.*/
        new Handler().postDelayed(new Runnable(){
            @Override
            public void run() {
                /* Create an Intent that will start the Menu-Activity. */
                Intent mainIntent = new Intent(Splash.this,Menu.class);
                Splash.this.startActivity(mainIntent);
                Splash.this.finish();
            }
        }, SPLASH_DISPLAY_LENGHT);
    }
}

XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <ImageView android:id="@+id/splashscreen" android:layout_width="wrap_content"
                android:layout_height="fill_parent" android:src="@drawable/cat"
                android:layout_gravity="center"/>
        <TextView android:layout_width="fill_parent"
                android:layout_height="wrap_content" android:text="Hello World, splash"/>
</LinearLayout>

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.carouseldemo.main"
      android:versionCode="1"
      android:versionName="1.0"
      >

    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" android:screenOrientation="portrait"/>
    <application android:icon="@drawable/buttonone" android:label="@string/app_name">

        <activity android:name=".MainActivity" android:label="@string/app_name" android:screenOrientation="portrait" android:configChanges="orientation|keyboardHidden" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
</manifest>

private static final int STOPSPLASH = 0;
private static final long SPLASHTIME =3000;



public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
            setContentView(R.layout.splash);
            context = getApplicationContext();
            if(savedInstanceState == null){
                Message msg = new Message();
                msg.what = STOPSPLASH;
                spHandler.sendMessageDelayed(msg, SPLASHTIME);
            }
        }   


    private Handler spHandler = new Handler() {
        @Override
        public void handleMessage(Message msg)
        {
            switch (msg.what)
            {
            case STOPSPLASH:
                gotoHomeScreen();
                break;
            default:
                break;
            }
            super.handleMessage(msg);
        }
    };

    public void gotoHomeScreen(){

        Intent i = new Intent();
            i.setClass(Splash.this,Home.class);
            startActivity(i);
            finish();
            spHandler = null;

    }

try this.

in your manifest

<activity android:name="Splash" android:configChanges="keyboardHidden" android:theme="@android:style/Theme.NoTitleBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
