eclipse Android创建相对布局和线性布局,主界面跳转

实验步骤

1.在之前创建的Android项目中添加两个新的Activity,右击src,选择NEW,选择最下面的other。

 

再点next

 

 

 

 再给自己的活动命名

 

 

 

2.我创建的两个Activity,一个是XiangDuiMainActivity相对布局一个是XianXinMainActivity线性布局(我拼音拼错了)创建成功后会有如下显示:

 

 

 

AndroidManifest中可以看到自己建立的两个activity

 

 

 3.下面一步是设计相对布局和线性布局,代码如下:

相对布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".XiangDuiMainActivity" >

 

    <ImageView

        android:id="@+id/imageView1"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_centerInParent="true"

        android:contentDescription="@string/description"

        android:src="@drawable/ic_launcher" />

 

    <ImageView

        android:id="@+id/imageView2"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_toLeftOf="@+id/imageView1"

        android:layout_centerVertical="true"

        android:contentDescription="@string/description"

        android:src="@drawable/ic_launcher" />

    <ImageView

        android:id="@+id/imageView3"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_toRightOf="@+id/imageView1"

        android:layout_centerVertical="true"

        android:contentDescription="@string/description"

        android:src="@drawable/ic_launcher" />

    <ImageView

        android:id="@+id/imageView4"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_above="@+id/imageView1"

        android:layout_centerHorizontal="true"

        android:contentDescription="@string/description"

        android:src="@drawable/ic_launcher" />

    <ImageView

        android:id="@+id/imageView5"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_below="@+id/imageView1"

        android:layout_centerHorizontal="true"

        android:contentDescription="@string/description"

        android:src="@drawable/ic_launcher" />

    <ImageView

        android:id="@+id/imageView7"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_alignLeft="@+id/imageView3"

        android:layout_below="@+id/imageView5"

        android:layout_marginTop="15dp"

        android:layout_marginLeft="15dp"

        android:contentDescription="@string/description"

        android:src="@drawable/pic2" />

    <ImageView

        android:id="@+id/imageView6"

        android:layout_width="80dp"

        android:layout_height="80dp"

        android:layout_marginTop="15dp"

        android:layout_marginLeft="15dp"

        android:contentDescription="@string/description"

        android:src="@drawable/pic3" />

    

</RelativeLayout>

主界面

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/pic1"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_marginBottom="18dp"
        android:layout_marginRight="25dp"
        android:text="@string/xiangdui" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/button2"
        android:layout_alignBottom="@+id/button2"
        android:layout_alignLeft="@+id/textView1"
        android:layout_marginLeft="24dp"
        android:text="@string/xianxing" />

</RelativeLayout>

 

还有就是主界面Activity的跳转代码

 

package com.example.test;

import com.example.test.R;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity  {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button1 = (Button)findViewById(R.id.button1);
        Button button2 = (Button)findViewById(R.id.button2);
        button1.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
                //点击后执行
                Intent intent = new Intent(MainActivity.this,XianXinMainActivity.class);
                startActivity(intent);
            }        
        });
        button2.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
                //点击后执行
                Intent intent = new Intent(MainActivity.this,XiangDuiMainActivity.class);
                startActivity(intent);
            }        
        });
    
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    
}

4.运行结果
