Question

I use tablelayout instead of the custom header title bar

Now my layout like the xml I show below, and I want to put the 2 icon and the text align right, but when I use android:layout_gravity="right" it seems not work, so how can I do it ?

This is my layout xml:

  < ? xml version="1.0" encoding="utf-8"?>
  < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >    
        <TableLayout
            android:id="@+id/tableLayout1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:background="#4494D1" >

            <TableRow
                android:id="@+id/tableRow1"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="right" >

                <LinearLayout
                    android:id="@+id/linearLayout3"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="vertical" >

                    <TextView

                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_gravity="center_vertical"
                        android:text="简易尺子" 
                        android:textColor="#fff"
                        android:textSize="25dp"
                        android:layout_marginTop="5dp"
                         android:layout_marginLeft="15dp"
                        />

                </LinearLayout>

                <LinearLayout
                    android:id="@+id/linearLayout1"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:orientation="vertical" 

                    >

                    <ImageButton

                        android:layout_marginTop="5dp"/>

                    <TextView

Answer 1

The layout gravity you set is not to affect the positioning of the TextView and the ImageView in the TableRow, rather it will position them in the wrapping LinearLayout which is not quite what you need. I suggest you define the following attribute to your TableLayout:

<TableLayout
    android:layout_width="fill_parent"
    android:layout_width="wrap_content"
    android:stretchColumns="0,1">

This will make the first two columns of the raw expand and thus shrink the rightmost column to the right.

NOTE (IMPORTANT) Currently you do not have a valid layout defined: you have a TableRow in LinearLayout – this is not allowed – you should place the row in TableLayout like the one I have defined.
