Hi, I am trying to reuse a dialog to show different message in different cases. But it seems that Android will cache the content, when the dialog was created. Here is my codes, the dialog just show the content set by the the first clicked button. ------------------------------------------------------------------------------------------------------------------------------ package com.mytest; import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.DialogInterface; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class myTest extends Activity { public static String errTitle = ""; public static String errMessage = ""; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button bt1 = (Button)findViewById(R.id.Button01); Button bt2 = (Button)findViewById(R.id.Button02); bt1.setOnClickListener(new OnClickListener(){ public void onClick(View v){ errTitle = "H1"; errMessage = "M1"; showDialog(0); } }); bt2.setOnClickListener(new OnClickListener(){ public void onClick(View v){ errTitle = "H2"; errMessage = "M2"; showDialog(0); } }); } protected Dialog onCreateDialog(int id) { AlertDialog dialog = null; switch (id){ case 0: dialog = new AlertDialog.Builder(this) .setTitle(errTitle) .setMessage(errMessage) .setPositiveButton( "Confirm", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { dialog.dismiss(); return; } }).create(); } return dialog; } } --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
