Question

当我使用findVewById（布局setcontextview（R.layout.main））时，我在single_item.xml中输入id“@ + id / call”。应用程序崩溃。如何修复错误代码single_items.xml用于在类CustomSqlCursorAdapter中扩展listView

<?xml version="1.0" encoding="utf-8"?>

class managecontact.java

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mDbHelper = new database(this);
    mDbHelper.open();


    /* ImageView call=(ImageView)this.findViewById(R.id.call);
     call.setOnClickListener(new OnClickListener() {


        @Override
        public void onClick(View v) {
            //TODO Auto-generated method stub
            call();
        }                
     });*/



    registerForContextMenu(getListView());
}


private void fillData() {

    Cursor currentCursor = mDbHelper.fetchAllNotes();
    startManagingCursor(currentCursor);

    // Create an array to specify the fields we want to display in the list (only TITLE)
    String[] from = new String[]{database.KEY_TITLE};

    // and an array of the fields we want to bind those fields to (in this case just text1)
    int[] to = new int[]{ R.id.contact_name};

    // Now create a simple cursor adapter and set it to display
    CustomSqlCursorAdapter adapter = new CustomSqlCursorAdapter(this, R.layout.single_item,currentCursor, from, to);
    setListAdapter(adapter);

}
private void call() {

    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:123456789"));
    startActivity(callIntent);

}

我想在点击图片图标时拨打电话。请告诉我如何更正

您可能在自定义ListAdapter中使用了inflater
在这方面，可能已经完成了不完全相同的事情。
`如果（） { LinearLayout ll = yourInflater.inflate（....）; else {ll =（LinearLayout）convertView;}
为了获得呼叫ID，请执行以下操作： `ImageView call = ll.findViewById（r.id.call）;

希望它会帮助你............
