自定義ListView

import android.annotation.TargetApi;
import android.content.Context;
import android.os.Build;
import android.util.AttributeSet;
import android.widget.ListView;

public class MyListView extends ListView {
    public MyListView(Context context) {
        super(context);
    }

    public MyListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyListView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public MyListView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // 設計一個較大的值和AT_MOST模式
        int newHeightMeasureSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> , 
                MeasureSpec.AT_MOST);
        // 調用原方法測量
        super.onMeasure(widthMeasureSpec, newHeightMeasureSpec);
    }
}
