android - 计时器 Activity 错误

Question

我的 Activity 有一个计时器，它会改变 Activity 与另一个 Activity 在 AVD 上工作正常但在真实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);

这里是 logcat 输出:

如果需要信息，我的设备是 Galaxy s4。

这是我的图像适配器代码，应该在哪里输入 picasso 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;
}

解决问题的最快方法是使用 Jake Wharton 的 Picasso 库。它可以在一行代码中加载图像并管理缓存、转换、下载等。

这是下载库的链接: 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);

将它放在您的网格适配器中，提供图像 URL 或可绘制对象或...并用您的图像持有者替换 imageView。

它应该像一个魅力:)
