Hallo!
ich habe eine TableView mit TextViews.
Ich möchte, dass alle meine Spalten gleichbreit sind, jedoch wenn ich text hinzufüge, wird die Breite verändert. Dies darf NICHT passieren!

XML: 
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ScheduleFragment">

    <TableLayout
        android:id="@+id/grid"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:stretchColumns="*"
        android:collapseColumns="*"
        android:shrinkColumns="*"></TableLayout>

</FrameLayout>

    }


    public class ScheduleCell extends LinearLayout {
        Subject subject;

        public ScheduleCell(Context context, Subject subject) {
            super(context);
        this.subject = subject;
        setBackgroundResource(R.drawable.schedule_item_border);


        TextView tvName =new TextView(context);
        tvName.setText(subject.getName());
        this.addView(tvName);

        }
        @Override
        protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
            super.onMeasure(widthMeasureSpec, widthMeasureSpec); // force square shape
        }
    }


}



Hat wer eine Idee, wie ich das anstelle?
