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"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#f6f6f6"
android:orientation="vertical" >

<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="52dip"
android:layout_gravity="center"
android:background="#d80702" >

<TextView
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center"
android:paddingLeft="15dip"
android:text="双色球-普通"
android:textColor="#ffffff"
android:textSize="18sp" />
</RelativeLayout>

<RelativeLayout

android:visibility="visible" />

<com.example.testxiala.Scrllon_view
android:id="@+id/main_relative_scrllon_view"
android:layout_width="match_parent"
android:layout_height="fill_parent" >

<LinearLayout

android:layout_height="40dip"
android:background="#aabbcc"
android:gravity="center"

android:textColor="#222222"
android:visibility="visible" />

<TextView
android:id="@+id/main_textiview1"
android:layout_width="fill_parent"
android:layout_height="200dip"
android:background="#cbacba"
android:gravity="center"
android:text="这里是选球界面,红球"
android:textColor="#d80702"
android:visibility="visible" />

<TextView
android:id="@+id/main_textiview2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#abcabc"
android:gravity="center"
android:text="这里是选球界面,篮球"
android:textColor="#d80702"
android:visibility="visible" />
</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:layout_width="fill_parent"
android:layout_height="52dip"
android:background="#f8f8f8"
android:orientation="horizontal" >

<TextView
android:id="@+id/ssq_main_txt_mainConfirm"
android:layout_width="80dp"
android:layout_height="36dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:gravity="center"
android:text="投注"
android:textColor="#222222"
android:textSize="16sp"
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？？？
