问题描述

I am creating a custom dialog where I want to put ImageView on center top of dialog box how this can be done.

推荐答案

您可以根据自己的想法将Views放在LinearLayout内.

You can put your Views, inside LinearLayout as per your idea.

对话方法:

Dialog dialog = new Dialog(this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.mhp);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    dialog.show();  

mhp.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/transparent" >

<LinearLayout
    android:id="@+id/linearLayout1"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="57dp"
    android:background="#f00"
    android:orientation="vertical" >
</LinearLayout>

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:src="@drawable/ic_launcher" />

</RelativeLayout>  

结果(避免BG)
