Glide加载图片查看报错信息

Glide为我们提供了listener（）方法，加上它就能看到报错信息了，查看log：

package com.kite.imageloader;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ImageView;
import android.widget.Toast;

import com.bumptech.glide.Glide;
import com.bumptech.glide.load.resource.drawable.GlideDrawable;
import com.bumptech.glide.request.RequestListener;
import com.bumptech.glide.request.target.Target;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";
    ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView = (ImageView) findViewById(R.id.image);
        Toast.makeText(this, "kkk", Toast.LENGTH_SHORT).show();
                Glide.with(this).load("http://7xi8d6.com1.z0.glb.clouddn.com/16124047_121657248344062_4191645221970247680_n.jpg")
                .listener(mRequestListener)
                .into(imageView);

   RequestListener mRequestListener = new RequestListener() {
        @Override
        public boolean onl oadFailed(@Nullable GlideException e, Object model, Target target, boolean isFirstResource) {
            Log.d(TAG, "onException: " + e.toString()+"  model:"+model+" isFirstResource: "+isFirstResource);
            imageView.setimageResource(R.mipmap.ic_launcher);
            return false;
        }

        @Override
        public boolean onResourceReady(Object resource, Object model, Target target, DataSource dataSource, boolean isFirstResource) {
            Log.e(TAG,  "model:"+model+" isFirstResource: "+isFirstResource);
            return false;
        }
    };
}
