TextView with custom styling throwing weird inflate exception
I am working on an android project and am creating my own list view. The list view contains multiple views of the text and I am creating a style for my text view so I don't have to repeat the same style over and over.
Below is my layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/txtFirstOccurred"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
style="@style/CrashGroup"/>
<TextView android:id="@+id/txtLastOccurred"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
style="@style/CrashGroup"/>
</LinearLayout>
Below is my style for my textview
<style name="CrashGroup">
<item name="android:singleLine">false</item>
<item name="android:textSize">@android:style/TextAppearance.Small</item>
<item name="android:gravity">center_vertical</item>
</style>
Below is how I inflate my XML so that it appears in my list.
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
try
{
convertView = LayoutInflater.from(getContext()).inflate(R.layout.android_crash_group_layout, null);
TextView txtFirstOccurred = (TextView)convertView.findViewById(R.id.txtFirstOccurred);
txtFirstOccurred.setText(getItem(position).getFirstOccurred());
TextView txtLastOccurred = (TextView)convertView.findViewById(R.id.txtLastOccurred);
txtLastOccurred.setText(getItem(position).getLastOccurred());
return convertView;
}
catch (Exception ex)
{
Log.e(TAG, ex.toString());
return null;
}
}
I get an error:

It seems to have something to do with the style, as if I am removing this style attribute from the text views, it seems to work fine.

I think the one that convertView
you return is null
from time to time because the conversionView handling is tricky.
Make sure you have a value. You can use smth like:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
TextView text = null;
if (convertView == null) {
convertView = inflater.inflate(R.layout.listrow_details, null);
}
text = (TextView) convertView.findViewById(R.id.textView1);
text.setText(children);
return convertView;
}
Hope it helps.
