Question

我在代码中使用自定义布局的对话框;
问题是我对如何显示带标题的图标感到困惑。

我没有使用警告对话框：我正在使用对话框以下是我的代码当我使用这一行时：

// dialog2.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON, R.drawable.ic_launcher);

应用程序崩溃

  dialog2 = new Dialog(context);
    View vLoad = LayoutInflater.from(ActivityHome.this).inflate(
            R.layout.timer, null);

    dialog2.setContentView(vLoad);
    TextView text1 = (TextView) dialog2.findViewById(R.id.text1);
    TextView text2 = (TextView) dialog2.findViewById(R.id.text2);

    Button closedailog = (Button) dialog2.findViewById(R.id.dailogexit);


    String next = "<font color='#EE0000'>red</font>";

   String[]     documentlisencearray = documentlisence.split(",");

    if(documentlisencearray[1]!=null)
    {String newString1 = new String(documentlisencearray[1].toString());
    String[]        documentobject = newString1.split("=");

     text1.setText(documentobject[0]);
     text2.setText(documentobject[1]);
    }

    dialog2.setTitle("Documents Due Alert");

    dialog2.setTitle( Html.fromHtml("<font color='#ff0000'>Documents Due Alert</font>"));
//  dialog2.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON, R.drawable.ic_launcher);
    dialog2.setCancelable(false);
    dialog2.show();

        closedailog.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                //
                dialog2.dismiss();
            }
        });

}

Answer 1

这是解决方案

final Dialog dialog = new Dialog(this);
**dialog.requestWindowFeature(Window.FEATURE_LEFT_ICON);**
dialog.setTitle(R.string.my_dialog_title);
dialog.setContentView(R.layout.my_dialog_layout);
dialog.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON,R.drawable.some_icon);
dialog.show();

Answer 2

您需要将此用于对话

dialog.requestWindowFeature(Window.FEATURE_LEFT_ICON);
dialog.setContentView(R.layout.yourlayoutfile);
dialog2.setTitle("Documents Due Alert");

dialog.show();
dialog.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON, R.drawable.your_icon)
