使用说明：

}

Maven

<dependency>
  <groupId>com.miao</groupId>
  <artifactId>freesizedraggablelayout</artifactId>

Use it in your own code:

1. xml:

    <com.miao.freesizedraggablelayout.FreeSizeDraggableLayout
        android:id="@+id/fsd_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

2.设置

FreeSizeDraggableLayout fsdLayout = (FreeSizeDraggableLayout) findViewById(R.id.fsd_layout);
fsdLayout.setUnitWidthNum(4);
fsdLayout.setUnitHeightNum(4);

3.创建一个 DetailView 列表:

List<DetailView> list = new ArrayList<>();
/*
DetailView:
public DetailView(Point p, int width, int height, View v) {
    setPoint(p);
    setWidhtNum(width);
    setHeightNum(height);
    setView(v);
}
*/
list.add(new DetailView(new Point(0, 0), 2, 2, createButton(1)));
list.add(new DetailView(new Point(2, 0), 2, 2, createButton(2)));
list.add(new DetailView(new Point(0, 2), 2, 2, createButton(3)));
list.add(new DetailView(new Point(2, 2), 2, 2, createButton(4)));
/*
private Button createButton(int i) {
    final Button btn = new Button(getApplicationContext());
    btn.setText("Button - " + i);
    btn.setBackgroundColor(Color.BLACK);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplicationContext(), btn.getText(), Toast.LENGTH_SHORT).show();
        }
    });
    return btn;
}
*/

4.set the list as ViewGroup's datasource把这个列表作为freeSizeDraggableLayout的数据源

freeSizeDraggableLayout.setList(list);
