DIsable scrolling for listview and enable for whole layout

问题

Hi iam currently working on an android application it has two list views inside the main activity.What i want is disable the scrolling of two lists and allow the whole page to scroll only,is there any way for that please do help..... my code package com.example.listviewdemo;

 import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
 import android.view.View;
 import android.widget.AdapterView;
 import android.widget.ArrayAdapter;
 import android.widget.ListView;
 import android.widget.Toast;

public class MainActivity extends Activity {

ListView list,list2;
String[] name={"Happy","always","try","hard","you will","get it!","Believe","in","God","everything","will","work well!","Believe","in","God","everything","will","work well!"};
String[] name2={"Believe","in","God","everything","will","work well!","Believe","in","God","everything","will","work well!"};
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    list = (ListView) findViewById(R.id.listview);
    list2 = (ListView) findViewById(R.id.listview2);
    list.setAdapter(new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,name));
  list2.setAdapter(new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,name2));



    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            // TODO Auto-generated method stub

            Toast.makeText(getBaseContext(), name [position],Toast.LENGTH_SHORT).show();
        }
    });

list2.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            // TODO Auto-generated method stub

            Toast.makeText(getBaseContext(), name2 [position],Toast.LENGTH_SHORT).show();
        }
    });   
}   
  }

my xml code is:

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
     android:layout_width="match_parent"
    android:layout_height="match_parent"
     android:orientation="vertical"
     tools:context="${relativePackage}.${activityClass}" >
    <TextView
    android:id="@+id/text_id1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
  android:text="@string/str1" />
   <ListView
    android:id="@+id/listview"
    android:layout_width="match_parent"
     android:layout_height="wrap_content"
    />
    <TextView
      android:id="@+id/text_id2"
     android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="@string/str2" 

     />

      <ListView
    android:id="@+id/listview2"
    android:layout_width="match_parent"
     android:layout_height="wrap_content"
       />
      </LinearLayout>

You can try this.

FOR xml PART DO THIS:

Put your entire layout data under one Scroll View, for example:

    <ScrollView
        android:id="@+id/scrollViewId"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true" >             

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

                <ListView
                    android:id="@+id/list"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" /> // SAY YOUR FIRST LIST VIEW:

                <ListView
                    android:id="@+id/list"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" /> // SAY YOUR SECONDLIST VIEW:

                 // Add your other views as per requirement....

        </LinearLayout>

    </ScrollView>

NOW IN JAVA CLASS DO THE FOLLOWING THING...

Just add this custom method to your code after setting adapter to list view:

setListViewHeightBasedOnChildren(listview)

For Example:

      list = (ListView) findViewById(R.id.listview);
      list.setAdapter(new ArrayAdapter<String> 
                      (MainActivity.this,android.R.layout.simple_list_item_1,name));
      setListViewHeightBasedOnChildren(list);

Do it same for second list view too.

Here is body of setListViewHeightBasedOnChildren METHOD

   public static void setListViewHeightBasedOnChildren(ListView listView) 
{
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null)
        return;

    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.UNSPECIFIED);
    int totalHeight=0;
    View view = null;

    for (int i = 0; i < listAdapter.getCount(); i++) 
    {
        view = listAdapter.getView(i, view, listView);

        if (i == 0)
            view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth,  
                                      LayoutParams.MATCH_PARENT));

        view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += view.getMeasuredHeight();

    }

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + ((listView.getDividerHeight()) * (listAdapter.getCount()));

    listView.setLayoutParams(params);
    listView.requestLayout();

}

Hope it works for you.

You shouldn't put scrolling container inside other scrolling container (ScrollView containing listView) Even if you manage to make it work it will create problems.

Please consider redesign of your layout or e.g. dynamically add layouts to scroll view or get rid of scroll view and use list view with header and/or footer views

回答3:

scroolview allow only one child. so to solve your problem you need to create scrollview in the xml inside put linearLayout and inside the LinearLayout put all your content.

and for disabling the list scrolling you can use inside MainActivty : list .setVerticalScrollBarEnabled(false);

<ScrollView
       android:id="@+id/scrollView1"
       android:layout_width="match_parent"
       android:layout_height="match_parent" >
       <LinearLayout
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:orientation="vertical" >
           <TextView
               android:id="@+id/text_id1"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:text="@string/str1" 
               />
           <ListView
               android:id="@+id/listview"
               android:layout_width="match_parent"
               android:layout_height="wrap_content" >
           </ListView>
           <TextView
               android:id="@+id/text_id2"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:text="@string/str2" />
           <ListView
               android:id="@+id/listview2"
               android:layout_width="match_parent"
               android:layout_height="wrap_content" >
           </ListView>
       </LinearLayout>
   </ScrollView>
