如何使我的列表视图行的高度不同

Question

Right now if there is a list item that is 2 lines in height then all the rows are two lines in height

How can I make the rows' height independent on other rows.

ListView

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

    <ListView
        android:id="@+id/user_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="@null" />

</LinearLayout>

Row

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:paddingBottom="1dp"
    android:paddingTop="1dp"
    android:paddingLeft="8dp"
    android:paddingRight="8dp" >

    <TextView
        android:id="@+id/user_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0"
        android:maxLines="2"
        android:ellipsize="middle"
        android:textColor="@android:color/holo_blue_dark"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/points"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="1"
        android:gravity="right"
        android:textStyle="bold" />

</LinearLayout>

I am using a custom adapter extending BaseAdapter. the getView there is nothing special, just a viewholder patern I don't change height or anything

Answer 1

why don't you try making the height = 0dp and weight 1

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:paddingBottom="1dp"
    android:paddingTop="1dp"
    android:paddingLeft="8dp"
    android:paddingRight="8dp" >

    <TextView
        android:id="@+id/user_name"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:maxLines="2"
        android:ellipsize="middle"
        android:textColor="@android:color/holo_blue_dark"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/points"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_gravity="right"
        android:layout_weight="1"
        android:gravity="right"
        android:textStyle="bold" />

</LinearLayout>

Answer 2

You are restricting it the TextView to have a maximum of 2 lines. It will never grow more than that. Remove android:maxLines="2" . It should work automatically.

Answer 3

The trick for me was not setting the height -- but instead setting the minHeight. This must be applied to the root view of whatever layout your custom adapter is using to render each row.

android:textAppearance="?android:attr/textAppearanceLarge" 

seemed no effect.

android:minHeight="?android:attr/listPreferredItemHeight" 

changed the height for me

Looks like you'll have to make visibility of your text views to be View.GONE when they are empty. You can do it in adapter implementation.

pointsView.setText(pointsText);
pointsView.setVisibility(TextUtils.isEmpty(pointsText) ? View.GONE : View.VISIBLE);

But be careful since your views are in RelativeLayout and its rules can stop working when an anchored view gets visibility View.GONE .

In such case you may try setting text size to zero instead of changing the view visibility, but I haven't tried it myself.

pointsView.setTextSize(TextUtils.isEmpty(pointsText) ? 0 : defaultSize);

If you are not limited with the TextView MaxLine then please remove android:maxLines="2" this will automatically adjust the height of list.
If you are looking for increasing the height of one particular row independent of others. After setting the adapter value for the list. Get the list
final ListView lv = getListView(); then form the lv get the particular row by
lv.getItemIdAtPosition(position) or any similar logic that best suited in your code. and change the row appearance programmatically as you looking for. Thanks.
