android - 自定义对话框显示错位的内容

Question

在下面发布的代码中，我是如何自定义我的 Dialog 的。但是本应填充Dialog 的内容放错了位置，或者不在Dialog 的相应位置。例如，单词“Report”应该与 icon 一起放置在 dialog 的上部，但正如您在图片中看到的，它们被放置在下方分隔 title 和 icon 上半部分以及 dialog 其余部分的线。如何纠正？

请同时查看输出图像和代码。

Java代码:

Dialog reportAlertDialog = new Dialog(MeetingPointFix.this);
            LayoutInflater reportAlertDialogLayoutInflater = LayoutInflater.from(getApplicationContext());
            View reportAlertDialogInflatedView = reportAlertDialogLayoutInflater.inflate(R.layout.report_dialog, null);

            reportAlertDialog.setContentView(reportAlertDialogInflatedView);

            int [] viewsRefsIds = {R.id.reportLocNameValue, R.id.reportLocLatValue, R.id.reportLocLngValue, R.id.reportTimeValue,
                    R.id.reportDateValue, R.id.reportImgTitleValue, R.id.reportImgPathValue
            };
            TextView [] viewsVars = new TextView[viewsRefsIds.length];

            TextView reportAlertDialogMSG = (TextView) reportAlertDialog.findViewById(R.id.reportDialogMessageValue);
            TextView reportAlertDialogTitle = (TextView) reportAlertDialog.findViewById(R.id.reportDialogTitleValue);
            reportAlertDialogMSG.setText(REPORT_ALERT_DIALOG_MSG);
            reportAlertDialogTitle.setText(REPORT_ALERT_DIALOG_TITLE);

            for (int i=0; i<bundleVals.length; i++) {
                viewsVars[i] = (TextView) reportAlertDialog.findViewById(viewsRefsIds[i]);
                viewsVars[i].setText(bundleVals[i]);
            }
            reportAlertDialog.show();

Answer 1

你需要给alerdialog设置标题

 reportAlertDialog.setTitle(REPORT_ALERT_DIALOG_TITLE);// takes charactersequence as param

同理

 reportAlertDialog.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON,R.drawabl‌​e.some_icon); 

http://developer.android.com/reference/android/app/Dialog.html

您不需要自定义 ImageView 和 TextView 如果您不希望它们出现在对话框内容部分中，可以将其删除。

编辑:

The feature has not been requested

Dialog  dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_LEFT_ICON); // request the feature
dialog.setContentView(R.layout.customlayout);
dialog.setTitle("My Title");
dialog.show();
dialog.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON, R.drawable.ic_launcher);
// set the icson
