FlowLayout

A flowlayout on android.

Usage

Add the dependencies to your gradle file:

dependencies {
    compile 'com.chrischeng:flowlayout:1.1.2'
}

The usage is similar to listview and FlowAdapter is the bridge between a FlowLayout and the data that backs the list.

XML:

<com.chrischeng.flowlayout.FlowLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:fl_spacing_horizontal="15dp" //the spacing between view in one row.
        app:fl_spcaing_vertical="30dp" /> //adjacent row spacing.

You can also control the spacing in java code.

flowLayout.setHorizontalSpacing(50); //default is 12dp
flowLayout.setVerticalSpacing(50); //default is 12dp

Adapter:

@Override
public View getView(int position, ViewGroup parent) {
    TextView textView = new TextView(parent.getContext()); //inflate whatever you want just like android.widget.Adapter
    textview.setText(mDatas.get(position));
    return textView;
}

You can receive a callback when a child view's state has bean changed, and you can also set limit of max selected, just like this

flowLayout.setMaxSelectedNum(5);
flowLayout.setOnStateChangedListener(new OnStateChangedListener() {
    @Override
    public void onStateChanged(int pos, boolean isSelected) {
      ...
    }

    @Override
    public void onMaxNumSelected() {
  ...
    }
});
