如何在android的警报对话框的顶部角落放置关闭按钮?
将关闭按钮放在警报对话框的右上角。
我已将以下代码用于滚动和对话框
<ScrollView
android:id="@+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:scrollbars="vertical"
android:scrollbarAlwaysDrawVerticalTrack="true" >
<ImageVieandroid:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="200dp"
android:src="@drawable/ic_launcher" />
</RelativeLayout>
</ScrollView>
在java编码中我使用了下面的编码我想放一张图片来关闭对话框请帮忙
public void onClick(View v)
{
// TODO Auto-generated method stub
switch (v.getId())
{
case R.id.How_to_use:
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.description);
dialog.setTitle("How to use");
TextView text = (TextView) dialog.findViewById(R.id.description);
text.setText(R.string.Descr_How_to_use);
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
image.setOnClickListener(new OnClickListener()
{
// @Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
break;
default:
break;
}
