我正在尝试在单击按钮时执行动画。步骤如下 单击按钮..

1. 按钮图片改变
2. 动画播放
3. 显示下一个布局..

但是我得到了一个内存不足的异常..

当动画文件没有添加到项目时没有错误。但是自从加了动漫之后，问题就来了。

我在这里使用了 3 个类文件(home_screen、button_anime 和 home)

home_screen.java 接收按钮点击信息，改变按钮图像并传递给button_anime 类动画文件在button_anime.java 中启动，动画播放后下一个布局从home.java 显示

日志猫如下..

我的home_screen.java

home.setOnClickListener(new OnClickListener() { <-- error happens somewhere here

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        Bitmap b = BitmapFactory.decodeResource(getResources(),R.drawable.home1);
        Drawable d = new BitmapDrawable(getResources(),b); 
        home.setBackgroundDrawable(d); <-- this dose not work..
        Intent myIntent = new Intent(Home_Screen.this, Button_Anime.class);
        startActivity(myIntent);
    }
});

最佳答案

_img 是您的 ImageView 。你必须解码你的图像并设置它的大小，就像我正在做的那样。

 File imgFile = new File(_path); // path of your file
    if (imgFile.exists()) {
        FileInputStream fis = new FileInputStream(imgFile);
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = 8;
        options.inPurgeable = true;
        options.inScaled = true;
        Bitmap bm = BitmapFactory.decodeStream(fis, null,options);
       _img.setImageBitmap(bm);
