Answer 1

Change this android:layout_gravity="left"

into this,

 android:layout_gravity="left|center_vertical" 

or

android:layout_gravity="center_vertical"

for your TextView.

<TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="left|center_vertical" 
            android:layout_weight="1"
            android:text="text1"/>

Answer 2

Add android:layout_gravity="center_vertical" to your TextView tag. Change your TextView tag as below

 <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left|center_vertical"
        android:layout_weight="1"
        android:text="text1"/>

Answer 3

Using center_vertical :

 <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left|center_vertical"
        android:layout_weight="1"
        android:text="text1"/>

Answer 4

try this..

      <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

            <TextView
                android:id="@+id/sampleId"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:text="Center String"
                android:textColor="#FFFFFF"
                android:textSize="14sp"
                android:typeface="sans" />
        </LinearLayout>

Answer 5

在我的情况下，我必须将weight属性设置为1，否则layout_gravity不会生效。

android:layout_weight="1"

Answer 6

Simply change TextView 's android:layout_height to match_parent , this should do the job. Hope this helps.
