Question

我的活动计时器改变活动与其他活动在AVD上工作正常但在实际设备中我得到的错误是代码：

new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
        final Intent mainIntent = new Intent(splash.this,MainActivity.class);
        splash.this.startActivity(mainIntent);
        splash.this.finish();
        }
        }, 5000);

这是logcat输出：

如果需要信息，我的设备是Galaxy s4。

我的图像适配器代码在哪里应该输入毕加索代码？

public class ImageAdapter extends BaseAdapter {
private Context mContext;

// Keep all Images in array
public Integer[] mThumbIds = {
        R.drawable.pic1,R.drawable.pic2,
        R.drawable.pic3,R.drawable.pic4,
        R.drawable.pic5,R.drawable.pic6,
        R.drawable.pic7,R.drawable.pic8,
        R.drawable.pic9,R.drawable.pic10,
        R.drawable.pic11,R.drawable.pic12,
        R.drawable.pic13,R.drawable.pic14,
        R.drawable.pic15,R.drawable.pic16,
        R.drawable.pic17,R.drawable.pic18,
        R.drawable.pic19,R.drawable.pic20,
        R.drawable.pic21,R.drawable.pic22,
        R.drawable.pic23,
        R.drawable.pic25,R.drawable.pic26,
        R.drawable.pic27,R.drawable.pic28,
        R.drawable.pic29,R.drawable.pic30,
        R.drawable.pic31,R.drawable.pic32,
        R.drawable.pic33,R.drawable.pic34,
        R.drawable.pic35,R.drawable.pic36,
        R.drawable.pic37,R.drawable.pic38,
        R.drawable.pic39,R.drawable.pic40,
        R.drawable.pic41,R.drawable.pic42,
        R.drawable.pic43,R.drawable.pic44,
        R.drawable.pic45,R.drawable.pic46,
        R.drawable.pic47,R.drawable.pic48,
        R.drawable.pic49,R.drawable.pic50,
        R.drawable.pic51,R.drawable.pic52,
        R.drawable.pic53,R.drawable.pic54,
        R.drawable.pic55


};

// Constructor
public ImageAdapter(Context c){
    mContext = c;
}

@Override
public int getCount() {
    return mThumbIds.length;
}

@Override
public Object getItem(int position) {
    return mThumbIds[position];
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {         
    ImageView imageView = new ImageView(mContext);
    imageView.setImageResource(mThumbIds[position]);
    imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
    imageView.setLayoutParams(new GridView.LayoutParams(250, 250));
    return imageView;
}

}

Answer 1

您尝试将大Bitmap加载到View时计时器不是错误。您无法加载位图，我建议使用maxDimension调整大小：（在这种情况下，它来自网址：input）

BitmapFactory.Options option = new BitmapFactory.Options();
option.inJustDecodeBounds = true;
Bitmap myBitmap = BitmapFactory.decodeStream(input, null, option);

int scale = 1;
if (option.outHeight > maxDimension || option.outWidth > maxDimension) {
    scale = (int) Math.pow(2, (int) Math.round(Math.log(maxDimension / (double) Math.max(option.outHeight, option.outWidth)) / Math.log(0.5)));
}

BitmapFactory.Options option2 = new BitmapFactory.Options();
option2.inSampleSize = scale;
myBitmap = BitmapFactory.decodeStream(input2, null, option2);

Answer 2

解决问题的最快方法是使用Jake Wharton的Picasso库。它允许在一行代码中加载您的图像并管理缓存，转换，下载等。

以下是下载图书馆的链接： http://square.github.io/picasso/

您需要的所有代码是：

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

将其放置在网格适配器中，提供图像URL或可绘制或...并替换图像持有者的imageView。

它应该像魅力一样：）

Answer 3

由于您要加载的图片太大，因此内存不足。它可能在第二个Activity的布局文件中设置，因此只有在您触发Error时才能获得Intent。这与计时器无关。你能解释一下这种情况并粘贴剩余的堆栈跟踪吗？
