TextView showing very small in the screen

Question

In my app I have the following layout, and no matter what value I give the textview doesn't change its width. Can someone please help me in correcting this layout.

Here is the XML code:

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_marginTop="15dp"
android:descendantFocusability="blocksDescendants" >

<TableRow
    android:layout_width="match_parent"
    android:gravity="center_horizontal" >

    <TextView
        android:id="@+id/rec_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/fill_rece"
        android:ems="10"
        android:focusable="false"
        android:padding="10dp"
        android:textColor="#FFFFFF" />

    <ImageButton
        android:id="@+id/btn_rec_delete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/content"
        android:src="@drawable/ipad_postcare_landscape_from" />
</TableRow>

</TableLayout>

I also get a warning near TableRow saying "This TableRow layout or its TableLayout parent is useless". Please guide me.

Thanks in advance.

Answer 1

Try this one Insted of table use Linear Layout with and set LAYOUT_WEIGHT property. This property shares the equal amount of space for text view and image button

<?xml version="1.0" encoding="utf-8"?>


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

<TextView
    android:id="@+id/rec_name"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:background="@drawable/fill_rece"
    android:focusable="false"
    android:padding="10dp"
    android:textColor="#FFFFFF" />

<ImageButton
    android:id="@+id/btn_rec_delete"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
     android:layout_weight="1"
    android:contentDescription="@string/content"
    android:src="@drawable/ipad_postcare_landscape_from" />
</LinearLayout>

try this....,you can add android:textSize="some value" which you want t o give

    <TextView
        android:id="@+id/rec_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:focusable="false"
        android:padding="10dp"
        android:text="hllo"
        android:textSize="25dp" />

You might need to use

android:layout_weight

I am mentioning one example for your help, also make sure your every element has height and weight with it, to display everything correctly

<LinearLayout  
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="@drawable/layout_border"
android:weightSum="1.0"
android:id="@+id/r1c1r2">
        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="0.5"
            android:textIsSelectable="true"
            android:id="@+id/key"/>
        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="0.5"
            android:textIsSelectable="true"
            android:id="@+id/key2" />
</LinearLayout>

Answer 4

Give the textsize using:

android:textSize="some value"

Answer 5

try to give size according to your requirement you have the width of the table row and textview set as match_parent hence it(textview) can't change it's size.

android:layout_width="50dp"
