Question

我无法弄清楚我做错了什么。我是一个完整的编码初学者，所以不要生气：）

基本上我想在我的闪屏中做一个动画背景。但每次启动它时，应用程序都会停止工作。

下面是代码和错误：

欢迎活动（启动）：

public class WelcomeActivity extends AppCompatActivity {

    private static int SPLASH_TIME_OUT = 4000;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcome);

        android.support.v7.app.ActionBar actionBar = getSupportActionBar();
        actionBar.hide();



        ImageView bgAni = (ImageView) findViewById(R.id.imageBG);
        bgAni.setBackgroundResource(R.drawable.animation_list);

        AnimationDrawable pro = (AnimationDrawable) bgAni.getBackground();
        pro.start();


        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent welcomeIntent = new Intent(WelcomeActivity.this, MainActivity.class);
                startActivity(welcomeIntent);
                finish();
            }
        }, SPLASH_TIME_OUT);

    }
}

主要活动：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

欢迎使用XML：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="de.procre.togetheraware.WelcomeActivity">

    <ImageView
        android:id="@+id/imageBG"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/animation_list"
        android:scaleType="fitXY"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:textColor="@color/pure_white"/>


</RelativeLayout>

动画列表：

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/anim_background" android:oneshot="true">
    <item android:drawable="@drawable/frame0000" android:duration="30" />
    <item android:drawable="@drawable/frame0001" android:duration="30" />
.
.
.
    <item android:drawable="@drawable/frame0124" android:duration="30" />

</animation-list>

Answer 1

在这里你的内存不足，应用程序无法分配必要的内存有一个解决方案，您可以将此行放在应用程序标记清单中

android:largeHeap="true"

Answer 2

尝试在makeiest文件的应用程序标记中make make android:hardwareAccelerated="false"和android:largeHeap="true" 像这样

<application
 android:largeHeap="true"
 android:hardwareAccelerated="false">

Answer 3

在您的清单中，application下包含以下内容：

<application
    ...
    ..
    .
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:largeHeap="true"
    android:supportsRtl="true"
    .
    ..
    ...>

在调用意图后取消你使用的finish();。

Answer 4

在<animation-list .......... </animation-list>中，您使用 124 drawables 制作动画，即使添加largeheap，这肯定会导致内存不足，这不是一个好习惯。请参考here此库以创建动画启动....或选择其他替代方案

应用停止工作
