推荐答案

您可以使用此布局：

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


    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="bottom" >

            <TextView
                android:id="@+id/textView1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Link:"
                android:textAppearance="?android:attr/textAppearanceMedium" />

            <LinearLayout

                    android:src="@drawable/settings" />

            </LinearLayout>

        </LinearLayout>

                android:layout_height="wrap_content"
                android:gravity="right" >

                <ImageView
                    android:id="@+id/imageView2"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/unnamed" />

            </LinearLayout>

        </LinearLayout>

        <LinearLayout

                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:ems="10" />
        </LinearLayout>

    </LinearLayout>

</RelativeLayout>

和java中code作为一般定义的TextView和ImageView的和...等。

and in java code as usually define textview and imageview and ... etc.

Button image1 = (Button) dialog.findViewById(R.id.imageView1);

.
.
.

dialog.show();
