android - TableRow中的LinearLayout不考虑分配的重力

我正在尝试在表行LinearLayout中添加一个programmatically。线性布局在XML中以重心为中心。但是它显示在表格行的左侧，如下所示

TableLayout定义如下：

    <RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="SELECT A VEHICLE"
        android:textColor="@color/select_vehicle"
        android:id="@+id/select_vehicle"
        android:textSize="28sp"
        android:textAppearance="?android:attr/textAppearanceSearchResultTitle"
        android:layout_marginTop="@dimen/activity_horizontal_margin"
        android:layout_centerHorizontal="true" />


<TableLayout
    android:layout_width="fill_parent"
    android:id="@+id/select_vehicle_table"
    android:layout_height="fill_parent"
    android:layout_below="@id/select_vehicle"
    android:layout_margin="@dimen/activity_horizontal_margin">


</TableLayout>

</RelativeLayout>

这是线性布局，它是表行的子视图：

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

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/vehicle_name"
        android:paddingTop="10dp"
        android:gravity="center"
        android:text="Vehicle Name"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="10dp"
        android:id="@+id/vehicle_number"
        android:gravity="center"
        android:paddingTop="5dp"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Vehicle Number" />

</LinearLayout>

这是我以编程方式设置它的方式，但是中心重力没有显示出来：

 mTableLayout = (TableLayout) findViewById(R.id.select_vehicle_table);
        LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        for(int i=0;i<2;i++)
        {

            TableRow tableRow = new TableRow(this);
            tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT,Gravity.END));
            tableRow.setBackgroundResource(R.drawable.row_border);


            View v = inflater.inflate(R.layout.table_row_linear_layout,null);
            TextView vehicle_name = (TextView) v.findViewById(R.id.vehicle_name);

            vehicle_name.setText(vehicle_name_array[i]);
            TextView vehicle_number = (TextView) v.findViewById(R.id.vehicle_number);
            vehicle_number.setText(vehicle_number_array[i]);

            tableRow.addView(v);
            mTableLayout.addView(tableRow);
        }

最佳答案

我只是以编程方式设置LL而错过了这一行代码

tableRow.setGravity(Gravity.CENTER_HORIZONTAL);
