android - 在 alertDialog android 中显示 ListView

Question

当用户单击列表项时，将显示一个对话框，其中包含“查看”、“删除”或“更新”等选项 ListView 项。第一次单击 ListView 项会显示带有选项的警报对话框，但是当我第二次单击另一个 ListView 项或同一个 ListView 项时，应用程序崩溃。提前致谢。

错误:java.lang.IllegalStateException:指定的子项已有父项。您必须先对 child 的 parent 调用 removeView()。

  //The main list displayed when the user log in successfully  
  ListView = (ListView) findViewById(R.id.list);
    ListView2 = new ListView(this);  //List to be displayed in the alert Dailog box     
    ListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            long i =  ListView.getItemIdAtPosition(position);
            showAlertDailog();//The dialog box method
        }
    });
    if(mCursorAdapter == null) //To check if the list is empty
    {
        TextView emptyTextView = (TextView) findViewById(R.id.empty);
        emptyTextView.setText("No Notes");
        ListView.setEmptyView(emptyTextView);
    }else {
        mCursorAdapter = new DataCursorAdapter(this, null);
        ListView.setAdapter(mCursorAdapter);
    }
 public void showAlertDailog()
{
    String [] items = {"View","Delete","Update"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.item_todo_2,R.id.textView4,items);
    ListView2.setAdapter(adapter);


    final android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(HomeActivity.this);
           builder.setView(ListView2)
            .setCancelable(false)
            .setPositiveButton("Close",null);
    android.app.AlertDialog alertDialog = builder.create();
    alertDialog.show();
}

Answer 1

ArrayList<String> arrayList = new ArrayList<String>();

CharSequence[] animals = arrayList.toArray(new String[arrayList.size()]);

        AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);

        dialogBuilder.setItems(animals, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int item) {

                String selectedText = animals[item].toString();
            }
        });

        AlertDialog alertDialogObject = dialogBuilder.create();

        alertDialogObject.show();

This is simple way to display list inside alert dialog, where in arraylist just add string whatever you have to display inside alert dialog list.
