Android(安卓)Dialog的四种情况

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;}
