Custom Adapter Setting values:

 @Override
public View getView(final int position, View convertView, ViewGroup parent)     {
    final Object[] id_obj=_id.toArray();
    Object[] name_obj=c_name1.toArray();
    Object[] mb_obj=m_no1.toArray();
    Object[] eml_obj=email1.toArray();
    ...
    Holder holder=new Holder();
    View rowView;       
         rowView = inflater.inflate(R.layout.report_custom_list, null);
         if(position%2==0)
             rowView.setBackgroundColor(Color.YELLOW);
         else
             rowView.setBackgroundColor(Color.GRAY);
         holder.tv=(TextView) rowView.findViewById(R.id.id);
         holder.tv1=(TextView) rowView.findViewById(R.id.nm);
         holder.tv2=(TextView) rowView.findViewById(R.id.mob);
         ...

         holder.tv.setText((CharSequence) id_obj[position]);
         holder.tv1.setText((CharSequence) name_obj[position]);
         holder.tv2.setText((CharSequence) mb_obj[position]);
         ...
     rowView.setOnClickListener(new OnClickListener() {            
     @Override
     public void onClick(View v) {
     }
     });

    return rowView;
 }

Before I hard coded the width for the textview. But if it goes to different screen the design collapse. How to fix this?

回答1:

Probably the problem is: ​​

<ListView 
    android:id="@+id/list_past_report"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</ListView>`

Replace layout_width="wrap_content" with layout_width="match_parent"



回答2:

change listviews layout_width to fill_parent

android:layout_width="fill_parent"


回答3:

I think you have to update you main layout file with this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

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

and make some changes in Adapter class also

public View getView(final int position, View convertView, ViewGroup parent)     {
final Object[] id_obj=_id.toArray();
Object[] name_obj=c_name1.toArray();
Object[] mb_obj=m_no1.toArray();
Object[] eml_obj=email1.toArray();
...
Holder holder=new Holder();
View rowView;       
     rowView = inflater.inflate(R.layout.report_custom_list, null);
     if(position%2==0)
         rowView.setBackgroundColor(Color.YELLOW);
     else
         rowView.setBackgroundColor(Color.GRAY);
     holder.tv=(TextView) rowView.findViewById(R.id.id);
     holder.tv1=(TextView) rowView.findViewById(R.id.nm);
     holder.tv2=(TextView) rowView.findViewById(R.id.mob);
     ...
     if(position == 0){
       holder.tv.setText("Title1");
       holder.tv.setText("Title2");
       holder.tv.setText("Title3");
       ....
     }
     else{
         holder.tv.setText((CharSequence) id_obj[position]);
         holder.tv1.setText((CharSequence) name_obj[position]);
         holder.tv2.setText((CharSequence) mb_obj[position]);
         ...
     }

 rowView.setOnClickListener(new OnClickListener() {            
 @Override
 public void onClick(View v) {
 }
 });

return rowView;}
