Android Dialog的四种情况 （转）

四种dialog总结，下面的代码返回的是一个Dialog，在onClick里面用showDialog（anyDialog）调用就可以。

一、一个确认一个取消

 private Dialog buildDialog1(Context context) {
  AlertDialog.Builder builder = new  AlertDialog.Builder(context);
  builder.setIcon(R.drawable.alert_dialog_icon);
  builder.setTitle(R.string.alert_dialog_two_buttons_title);
  builder.setPositiveButton(R.string.alert_dialog_ok,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {
      setTitle("点击了对话框上的确定按钮");
     }
    });
  builder.setNegativeButton(R.string.alert_dialog_cancel,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {
      setTitle("点击了对话框上的取消按钮");
     }
    });
  return builder.create();
 }

二、带有大量文本

private Dialog buildDialog2(Context context) {
  AlertDialog.Builder builder = new AlertDialog.Builder(context);
  builder.setIcon(R.drawable.alert_dialog_icon);
  builder.setTitle(R.string.alert_dialog_two_buttons_msg);
  builder.setMessage(R.string.alert_dialog_two_buttons2_msg);
  builder.setPositiveButton(R.string.alert_dialog_ok,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {
      setTitle("点击了对话框上的确定按钮");
     }
    });

  builder.setNeutralButton(R.string.alert_dialog_something,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {

      setTitle("点击了对话框上的进入详细按钮");
     }
    });
  builder.setNegativeButton(R.string.alert_dialog_cancel,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {
      setTitle("点击了对话框上的取消按钮");
     }
    });
  return builder.create();
 }

三、带输入框的，稍微复杂一点，要加人带textview、editview的layout

private Dialog buildDialog3(Context context) {
  LayoutInflater inflater = LayoutInflater.from(this);
  final View textEntryView = inflater.inflate(
    R.layout.alert_dialog_text_entry, null);
  AlertDialog.Builder builder = new AlertDialog.Builder(context);
  builder.setIcon(R.drawable.alert_dialog_icon);
  builder.setTitle(R.string.alert_dialog_text_entry);
  builder.setView(textEntryView);
  builder.setPositiveButton(R.string.alert_dialog_ok,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {
      setTitle("点击了对话框上的确定按钮");
     }
    });
  builder.setNegativeButton(R.string.alert_dialog_cancel,
    new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int whichButton) {
      setTitle("点击了对话框上的取消按钮");
     }
    });
  return builder.create();
 }

四、带进度条的

 private Dialog buildDialog4(Context context) {
  ProgressDialog dialog = new ProgressDialog(context);
  dialog.setTitle("正在下载歌曲");
  dialog.setMessage("请稍候……");
  return dialog;
 }
