<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
　　android:layout_width="match_parent"
　　android:layout_height="match_parent"
　　android:orientation="horizontal" >

<ImageView
　　android:id="@+id/diaimage"
　　android:layout_width="wrap_content"
　　android:layout_height="fill_parent" >
</ImageView>

<TextView
　　android:id="@+id/diatv"
　　android:layout_width="wrap_content"
　　android:layout_height="fill_parent" />

</LinearLayout>

<Button
android:id="@+id/btnshowdialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Show Dialog" />

  Button showdialog = (Button) findViewById(R.id.btnshowdialog);
  showdialog.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    AlertDialog dialog;
    LayoutInflater inflater = getLayoutInflater();
    View layout = inflater.inflate(R.layout.dialog, null);

    TextView diatv = (TextView) layout.findViewById(R.id.diatv);
    diatv.setText("Welcome to LayoutInflater study");
    ImageView image = (ImageView) layout.findViewById(R.id.diaimage);
    image.setImageResource(R.drawable.ic_launcher);

    builder.setView(layout);// <--important，设置对话框内容的View
    dialog = builder.create();
    dialog.show();
   }
  });
