Question

我正在尝试在Android中为我的应用创建一个启动画面，但它根本不会显示。我正在使用的代码是4个不同的文件。这是：

Splash.java

     package com.timchecklist;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;

public class Splash extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Thread Timer = new Thread() {
            public void run() {

                try {
                    sleep(3000);
                    startActivity(new Intent("com.timchecklist.SPLASHNEW"));

                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {
                    finish();
                }
            }
        };
        Timer.start();
    }

}

SplashNew.java

   package com.timchecklist;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class SplashNew extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.splash);

    }

}

Splash.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="@drawable/pic1"
    android:gravity="center"
    android:orientation="vertical" >

</LinearLayout>

的AndroidManifest.xml

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

    <uses-sdk android:minSdkVersion="7" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".TimCheckListActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar" >
        </activity>
        <activity
            android:name=".SplashNew"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

请告诉我这里我做错了什么。任何帮助，将不胜感激。谢谢你们:)）

Answer 1

我认为Splash should be launcher activity first。以及在AndroidManifest文件中声明SPLASHNEW的位置？

See Splash Screen Example

Answer 2

清单文件中没有Splash New的条目......

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

<uses-sdk android:minSdkVersion="7" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".TimCheckListActivity"
        android:label="@string/app_name" >

    </activity>

     <activity
        android:name=".Splash"
        android:label="@string/app_name" >
        <intent-filter>
           <action android:name="android.intent.action.MAIN" />
           <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>

</manifest>

您应该在清单文件中添加SplashNew。

尝试以下代码

 setContentView(R.layout.splash);

 new Thread(new Runnable() {

        public void run() {
                // TODO Auto-generated method stub      
                try {

                    Thread.sleep(2000);
                    startActivity(new Intent(getApplicationContext(),EquipmentCategory.class));
                    finish();

                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }
        }).start();

Answer 4

有更好的方法来制作闪屏。声明一个像这样的处理程序，它在预先准备好的时间后调用下一个要启动的活动：

private Handler splashHandler = new Handler() {

@Override
    public void handleMessage(Message msg) {
        switch (msg.what) {

            Intent intent = new Intent(Splash.this, OtherActivity.class);
            startActivity(intent);
            finish();

            break;
        }
        super.handleMessage(msg);
    }
};

然后在onCreate：

之后执行一些延迟后执行代码

Message msg = new Message();
splashHandler.sendMessageDelayed(msg, SPLASHTIME);

Android中的Splash无法正常工作
