我在android中的水平视图中有图像列表.如果我单击特定图像的图像视图必须以编程方式突出显示边框颜色.如何为图像视图的突出显示边框执行此操作.提前致谢.
当用户单击ImageView的单个图像时,我想显示像ImageView的这个边框.

您的活动中的ImageView
<ImageView
android:id="@+id/iv_test"
android:layout_width="150dp"
android:layout_height="150dp"
android:padding="3dp"
android:src="@drawable/yourImageName"
android:tint="@color/colorAccent"/>

内部活动代码
imv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Drawable highlight = getResources().getDrawable( R.drawable.highlight);
imv.setBackground(highlight);
//
//Do your other stuff here.
//
}
});

imv.setBackground(null);

在活动xml中,填充属性很重要,因为高亮背景将采用与imageview相同的大小.因此,如果imageview中有任何图像,我们将无法看到背景/突出显示.因此,padding属性将图像向内推一点,让高亮显示.

UPDATE
在你的代码中实现View.OnClickListener.
并更改您的onClick()方法
@Override
public void onClick(View v) {
Drawable highlight = getResources().getDrawable( R.drawable.highlight );
for (int j=0;j<ii.length;j++)
{
if (ii[j].getBackground()!=null) {
ii[j].setBackground(null);
}
}
v.setBackground(highlight);
//
//Do what you want to do when clicking on the imageview
//
}

现在你正在使用
ii=new ImageView(singleshooppingcart.this);

使它成为一个数组并像这样使用它
ii[i]=new ImageView(singleshooppingcart.this);
Run Code Online (Sandbox Code Playgroud)
改变这个
ii.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Drawable highlight = getResources().getDrawable(R.drawable.imgviewpress);
ii.setBackground(highlight);

至
ii[i].setOnClickListener(this);

这里我是循环变量.
这样,您将拥有所有imageView的对象.所有这些图像视图都将包含我们设置的ClickEvent.
