Q: How to make a listview with the same row height? In my Android app I am trying to make a ListView which has the same row height. For this I have created a xml layout for the row, which I am using in the adapter.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="10dip" >

    <TextView
        android:id="@+id/name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dip"
        android:textColor="@android:color/black"
        android:textSize="17dip" />

    <TextView
        android:id="@+id/comment"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="2dip"
        android:textColor="@android:color/black"
        android:textSize="14dip" />

    <TextView
        android:id="@+id/date"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="2dip"
        android:textColor="@android:color/black"
        android:textSize="14dip" />

</LinearLayout>

This is my adapter:

public class MyArrayAdapter extends ArrayAdapter<Sample> {

    private final Context context;
    private final Sample[] samples;

    public MyArrayAdapter(Context context, Sample[] samples) {
        super(context, R.layout.row_layout, samples);
        this.context = context;
        this.samples = samples;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View rowView = inflater.inflate(R.layout.row_layout, parent, false);
        TextView name = (TextView) rowView.findViewById(R.id.name);
        TextView comment = (TextView) rowView.findViewById(R.id.comment);
        TextView date = (TextView) rowView.findViewById(R.id.date);
        Sample sample = samples[position];

        name.setText(sample.getName());
        comment.setText(sample.getComment());
        date.setText(sample.getDate());

        return rowView;
    }

}

But the problem is that the row height is not same for all rows. How can I make the ListView with the same row height? A: ListView will adjust the row height to fit the content of the row. What you can do is set the minHeight attribute of the RowView:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="10dip"
    android:minHeight="50dp" >

This will set the minimum row height to 50dp.
