Android Dialog的四种情况_移动开发_编程开发_程序员俱乐部

看视频学android，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;
	}
