android对话框设置图标到标题

Question

我有这个对话框类,我想将图标设置为其标题:

public class DialogMealInformation extends Dialog implements
        android.view.View.OnClickListener {
    Context context;
    private TextView tv_information;
    private Button b_ok;
    private String information;

    public DialogMealInformation(Context context, String information) {
        // TODO Auto-generated constructor stub
        super(context);
        this.context = context;
        this.information = information;
        setContentView(R.layout.dialog_meal_information);
        getWindow().setLayout(android.view.ViewGroup.LayoutParams.FILL_PARENT,
                android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
        setTitle("Info !");

        initialize();
    }

它尝试这样:

setTitle(R.layout.dialog_simple_header);

dialog_simple_header.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/tv_dialog_simple_header_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tv_information"
        android:drawableLeft="@drawable/more_information" />

</LinearLayout>

但之后的标题是"res/layout/dialog_simple_header.x"只是文字,没有出现图标,请问为什么,解决方案是什么,非常感谢

在任何button单击或onActivity您希望此对话框显示的位置或任何位置上单击此按钮.每次都阅读我的评论//

AlertDialog alertDialog = new AlertDialog.Builder(
                    this).create();
            alertDialog.setTitle("TITLE"); // your dialog title 
            alertDialog.setMessage("Your message"); // a message above the buttons
            alertDialog.setIcon(R.drawable.ic_home); // the icon besides the title you have to change it to the icon/image you have. 
            alertDialog.setButton("Got IT", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) { // here you can add a method  to the button clicked. you can create another button just by copying alertDialog.setButton("okay")
                }

            });
alertDialog.show();

帮我一个忙,删除它

    public DialogMealInformation(Context context, String information) {
    // TODO Auto-generated constructor stub
    super(context);
    this.context = context;
    this.information = information;
    setContentView(R.layout.dialog_meal_information);
    getWindow().setLayout(android.view.ViewGroup.LayoutParams.FILL_PARENT,
            android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
    setTitle("Info !");

    initialize();
}

并添加我的!
