求解？Android自定义下拉，为什么只能获取到第一个控件的焦点了

我定义了一个下拉效果。但是只点击了他下面第一个控件才有效：

我点击或者触摸“这里是彩期显示区域”才会下拉出历史记录。我现在想要点击下面的红球、篮球选球区域也有效，怎么修改？？？？

java代码：

package com.example.testxiala;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends Activity {
	private Scrllon_view scrllon_view;
	private TextView lisi_textview;
	private TextView main_textview;
	private TextView main_textview2;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		scrllon_view = (Scrllon_view) findViewById(R.id.main_relative_scrllon_view);
		lisi_textview = (TextView) findViewById(R.id.lisi_textiview);
		main_textview = (TextView) findViewById(R.id.main_textiview1);
		main_textview2 = (TextView) findViewById(R.id.main_textiview2); 

		scrllon_view.setMaxHeight(100);
	}

}

xml布局代码：

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

            </LinearLayout>
        </com.example.testxiala.Scrllon_view>
    </RelativeLayout>

    <!-- 金额，确认选号 -->

    <View
        android:layout_width="fill_parent"
        android:layout_height="1px"
        android:background="#dedede" />

    <RelativeLayout

            android:textStyle="bold"
            android:typeface="monospace" />
    </RelativeLayout>

</LinearLayout>

还有我自定义的Scrllon_view

package com.example.testxiala;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.LinearLayout;
import android.widget.Scroller;

/**
 * LinearLayout换成RelativeLayout效果也是一样
 */
public class Scrllon_view extends LinearLayout {
	Scroller croller;

	private int moveY = 0;
	public boolean mEnabled = true;
	public int maxHeight = 0;

	public int getMaxHeight() {
		return maxHeight;
	}

	public void setMaxHeight(int maxHeight) {
		this.maxHeight = maxHeight;
	}

	public Scrllon_view(Context context) {
		super(context);
	}

	public Scrllon_view(Context context, AttributeSet set) {
		super(context, set);
		setDescendantFocusability(FOCUS_AFTER_DESCENDANTS);
		setFocusable(true);
		croller = new Scroller(context);

	}

	@Override
	public boolean onTouchEvent(MotionEvent event) {
		switch (event.getAction()) {
		case MotionEvent.ACTION_DOWN:
			return true;
		case MotionEvent.ACTION_MOVE:

			moveY = (int) event.getY();
			int Y = moveY;
			if (Y < maxHeight && moveY > 0) {
				scrollTo(0, -moveY);
			}
			break;
		case MotionEvent.ACTION_UP:
			int YY = (int) event.getY();
			if (YY < 100) {
				scrollTo(0, 0);
			} else if (YY > 250 && YY < maxHeight) {
				scrollTo(0, -(maxHeight));
			}
			break;
		default:
			break;
		}
		return super.onTouchEvent(event);
	}

	public void startMoveAnim(int startY, int dy, int duration) {
		croller.startScroll(100, startY, 100, dy, duration);
	}

	@Override
	public boolean onInterceptTouchEvent(MotionEvent ev) {
		if (mEnabled)
			return false;
		return super.onInterceptTouchEvent(ev);
	}

}

代码全部在上面，求解？？？
