Calling startActivity() from outside of an Activity? (11 个回答)

已关闭 9 年前。

我正在尝试自定义 ListView ，它工作正常，现在我已经在这部分getView方法中从baseAdapter进行了自定义类扩展，我正在imageview中应用onclickListener并启动新的Activity，这是崩溃的应用程序 代码

 public class CustomAdapterClass extends BaseAdapter
{
ArrayList<FatwaBean> fatwaArrayList;
Context context;

CustomAdapterClass(ArrayList<FatwaBean> data,Context c) {
    fatwaArrayList = data;
    context = c;
}
public int getCount() {
    // TODO Auto-generated method stub
    return fatwaArrayList.size();
}

public Object getItem(int position) {
    // TODO Auto-generated method stub
    return fatwaArrayList.get(position);
}

public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
     View v = convertView;
     if (v == null)
     {
        LayoutInflater vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.search_fatwa_row, null);
     }

      final ImageView image = (ImageView) v.findViewById(R.id.search_image_row);
       TextView dateTextView = (TextView)v.findViewById(R.id.search_date_row);

       FatwaBean fatwaBean= fatwaArrayList.get(position);
     //image.setImageResource(fatwaBean.getQuestionImage());
       image.setImageResource(R.drawable.app_icon);
      //image.setTag(fatwaBean.getFatwaTopicQuestionId());
       dateTextView.setText(fatwaBean.getFatwaDate());
       Log.i("fatwaBean",""+fatwaBean.getFatwaDate());
       Log.i("fatwaBean",""+fatwaBean.getFatwaImageName());
       Log.i("fatwaBean Topic Question Image Name",""+fatwaBean.getQuestionImage());

       image.setOnClickListener(new OnClickListener() {              
               public void onClick(View v) {
               // TODO Auto-generated method stub


               final int itemname= (int)fatwaArrayList.get(position).getFatwaTopicQuestionId();
               Log.i("clicked Fatwa Image Topic Id",""+fatwaArrayList.get(position).getFatwaTopicQuestionId());
               Intent intent = new Intent(context,FatwaZoomActivityImageView.class);
           //passing fatwa topic question Id to get FatwaImage in NextActivity

              intent.putExtra("questionTopicIdForFatwa",fatwaArrayList.get(position).getFatwaTopicQuestionId());
              intent.addFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
               context.startActivity(intent);

           }                        
       });
    return v;
}

Answer 1

按照 LogCat 中的建议，在 startActivity() 之前添加此内容。

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
