有時候，我們需要在一個ImageView上添加其它任何view。剛好LabelView能夠幫助你，實現起來很方便。

Import your project

Gradle

dependencies {
    compile 'com.lid.labelview:lib:0.1.1' }

If it doesn't work, please send me a emaillid.guan@gmail.comor create an issue.

Or

Copy LabelView.java into your project.

Create a Label

LabelView extends fromTextViewso you can treat it as aTextViewand use any of its method.

Usage:

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 states the distance between the edge of the bottom view and LabelView (unit dip)

• The third parameter states the side of where LabelView should appear on the bottom view. (onlyLEFT_TOPandRIGHT_TOP)

remove label

you can useremovemethod. 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;
}

setTargetViewInBaseAdapter parameters

• The second parameter means targetView width (unit dip).
