画像を見るたびにアプリケーションが終了します。なぜ説明できますか?Glide on Androidアプリでクラッシュする
おそらく問題は文字列Glide.with(getApplicationContext())
であると思われますが、それは正しくない可能性があります。 Android Studioの場合、エラーはありません。
他のすべての要素は正常ですが、問題は滑っているだけです。
public class MainActivity extends AppCompatActivity {
private final String url= "MY ARRAY";
...
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
new gson().execute(url);
}
public class gson extends AsyncTask<String,String, List<MovieModel> >{
....
public class Adapter extends ArrayAdapter{
private List<MovieModel> movieModelList;
private int resource;
private LayoutInflater inflater;
public Adapter(Context context, int resource, List<MovieModel> objects) {
super(context, resource, objects);
movieModelList = objects;
this.resource = resource;
inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if(convertView == null){
holder = new ViewHolder();
convertView = inflater.inflate(resource, null);
holder.fruitsfoto = (ImageView)convertView.findViewById(R.id.fruits);
holder.fruitsname = (TextView)convertView.findViewById(R.id.name);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
ImageView imageView = (ImageView) findViewById(R.id.pics);
final ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressBar);
try {
Glide.with(MainActivity.this)//getApplicationContext()
.load(ModelList.get(position).getImage())
.listener(new RequestListener<String, GlideDrawable>() {
@Override
public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
return false;
}
@Override
public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
progressBar.setVisibility(View.GONE);
return false;
}
})
.into(imageView);
} catch (Exception e) {
e.printStackTrace();
}
holder.fruitsname.setText(ModelList.get(position).getName());
return convertView;
}
}
}
更新:表示画像は配列のリストの後にありません。解決策が必要です。
public Adapter(Context context, int resource, List<MovieModel> objects) {
super(context, resource, objects);
ModelList = objects;
this.resource = resource;
inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
}
.....
try {
Glide.with(MainActivity.this)//getApplicationContext()
.load(ModelList.get(position).getFruits())
.into(imageView);
} catch (Exception e) {
e.printStackTrace();
}
編集:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if(convertView == null){
holder = new ViewHolder();
convertView = inflater.inflate(resource, null);
holder.fruitsfoto = (ImageView)convertView.findViewById(R.id.fruits);
holder.fruitsname = (TextView)convertView.findViewById(R.id.name);
1)holder.image = (TextView)convertView.findViewById(R.id.pics);
2)ImageView imageView = (ImageView)convertView.findViewById(R.id.pics);
convertView.setTag(holder);
//the first cause a crash
//the second return "Variable 'imageView is never used'"
これは、コンソールのエラーです:
