如何使用图像和滚动创建警报对话框[ANDROID]

Question

Dialog Java Code:

final Dialog dialog = new Dialog(context);
                dialog.setContentView(R.layout.custom_dialog);
                dialog.setTitle("Title...");
                ScrollView scroll = new ScrollView(context);
                scroll.setBackgroundColor(android.R.color.transparent);
                scroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                                                             LayoutParams.FILL_PARENT));    
                // set the custom dialog components - text, image and button
                TextView text = (TextView) dialog.findViewById(R.id.text);
                text.setText("Android custom dialog example!");
                ImageView image = (ImageView) dialog.findViewById(R.id.image);
                image.setImageResource(R.drawable.icon);
                dialog.show();

XML Code Here:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/layout_root"
          android:orientation="horizontal"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:padding="10dp"
          android:scrollbarAlwaysDrawVerticalTrack="true">
          >
<ImageView android:id="@+id/image"
           android:layout_width="wrap_content"
           android:layout_height="fill_parent"
           android:layout_marginRight="10dp"
           />
<TextView android:id="@+id/text"
          android:layout_width="wrap_content"
          android:layout_height="fill_parent"
          android:textColor="#FFF"
          />

I know that if i have only text on alert dialog it's automatically scrolling, but with an imageview automatically scrolling doesn't work. How can i fix this problem?

Put your layout inside a ScrollView:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" >

      <LinearLayout
          android:id="@+id/layout_root"
          android:orientation="vertical"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:padding="10dp"
          android:scrollbarAlwaysDrawVerticalTrack="true" >

          <ImageView android:id="@+id/image"
              android:layout_width="wrap_content"
              android:layout_height="fill_parent"
              android:layout_marginRight="10dp" />

          <TextView android:id="@+id/text"
              android:layout_width="wrap_content"
              android:layout_height="fill_parent"
              android:textColor="#FFF" />

    </LinearLayout>

<ScrollView>

I see that your LinearLayout has a horizontal orientation. So if this the case and you want to scroll horizontaly, you should replace ScrollView by HorizontalScrollView and set the orientation to horizontal.
Let me know if this works.
