问题
I have a custom listView. The listview data are setting by some textview horizontally for each rows. In main layout I have same number of textView for setting the title of those columns. My problem is, the main layout working fine with the weight property. But the custom value setting layout for listview which contains the textview is not working with the weight property.
Main Layout : (Weight property working correctly)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent">
<LinearLayout
android:layout_width="fill_parent"

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;}
