LabelView

Sometimes we need to show a label view above a ImageView or others, labelview will help you, let code easy.

import your project

you can copy LabelView.java file into you project.

create label

LabelView extended TextView so you can use TextView all method.

{
    LabelView label = new LabelView(this);
    label.setText("POP");
    label.setBackgroundColor(0xff03a9f4);
    label.setTargetView(findViewById(R.id.text), 10, LabelView.Gravity.LEFT_TOP);
}

setTargetView parameters

setTargetView(findViewById(R.id.text), 10, LabelView.Gravity.LEFT_TOP)

the second parameter means distance(unit dip).

the third parameter means gravity (only LEFT_TOP and RIGHT_TOP)

remove label

you can use remove method. eg:

label.remove();

LabelView in BaseAdpter

if you using LabelView in BaseAdpter and reuse of convertView, you have to generate label ID manual. eg:

public View getItemView(int position, View convertView, ViewHolder holder) {

    ......

    // you have to generate label ID manual
    LabelView label = holder.getView(12345);
    if (label == null) {
        label = new LabelView(this);
        label.setId(12345);
        label.setBackgroundColor(0xffE91E63);
        label.setTargetViewInBaseAdapter(imageView, 138, 10, LabelView.Gravity.LEFT_TOP);
    }
    label.setText(your data);
    return convertView;
}
