public void showPopup(int group,int img_index,JSONArray json_ar,View v){
PopupMenu pm=new PopupMenu(EditPhotosActivity.this,v);
pm.getMenuInflater().inflate(R.menu.popup_menu, pm.getMenu());
pm.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(getBaseContext(),"You Clicked : " + item.getTitle(),Toast.LENGTH_SHORT).show();
return false;
}
});
pm.show();
}
The showPopup方法由动态创建的 Imagevew 的 onclick 调用。应用程序在执行时崩溃pm.show().
这是错误日志。

/这是调用 showPopup 方法的代码片段/
LinearLayout ll_face=(LinearLayout) findViewById(R.id.face_linear);
// The above line of code is written inside onCreate method
ImageView imageView1=new ImageView(EditPhotosActivity.this);
imageView1.setPadding(3,3, 3,3);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT);
imageView1.setLayoutParams(layoutParams);
ll_face.addView(imageView1);
img_loader.DisplayImage(tmp_json_array.getJSONObject(j).getString("thumb_image"),imageView1);
final int group=i;
final int img_index=j;
imageView1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showPopup(group,img_index,json_ar,v);
}
});
