Android学习笔记——MixLayout

该工程的功能是实现LinearLayout+TableLayout

以下代码是MainActivity.java中的代码

package com.example.mixlayout;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

public class MainActivity extends Activity {

    private TextView firstText; 

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

以下代码是activity_main.xml中的代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    tools:context="${relativePackage}.${activityClass}" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:background="#aa0000"
            android:gravity="center_horizontal"
            android:text="red" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:background="#00aa00"
            android:gravity="center_horizontal"
            android:text="green" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:background="#0000aa"
            android:gravity="center_horizontal"
            android:text="blue" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >

        <TableLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:stretchColumns="1">
            <TableRow>

                <TextView
                    android:padding="3dip"
                    android:text="row1_column1" />

                <TextView
                    android:gravity="center_horizontal"
                    android:padding="3dip"
                    android:text="row1_column2" />

                <TextView
                    android:gravity="right"
                    android:padding="3dip"
                    android:text="row1_column3" />
            </TableRow>

            <TableRow>

                <TextView
                    android:padding="3dip"
                    android:text="row2_column1" />

                <TextView
                    android:gravity="center_horizontal"
                    android:padding="3dip"

                <TextView
