标签: java android animation out-of-memory

我正在尝试按下按钮执行动画..步骤如下 按钮点击..

  1. 按钮图像更改
  2. 动画播放
  3. 显示下一个布局..
  4. 但是我得到了内存异常......

    当动画文件未添加到项目时,没有错误。但是,由于动画的加入存在问题。

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

    home_screen.java接收按钮点击信息,更改按钮图像并转移到button_anime类,动画文件在button_anime.java中启动,动画播放后,下一个布局显示在home.java

    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);
        }
    });

_img是你的imageview。你必须解码你的图像并设置它的大小,如下所示。

 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);

答案 1 :(得分:0)

您应该使用decodeResource(Resources res, int id, BitmapFactory.Options opts),并指定inSampleSize -

  

如果设置为值&gt; 1,请求解码器对原始进行二次采样   图像,返回较小的图像以节省内存。
