今天学习的是安卓事件监听。实现了点击图片之后图片变化，声音。

想发送文件也不知道能不能发送。

重点：1 布局要布局好。<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=".MainActivity" >


<Button
android:id="@+id/sound"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginTop="10dip"
android:background="@drawable/bt_homepage_sound_on"/>

<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginLeft="10dip"
android:layout_marginTop="10dip"

android:background="@drawable/feedback"/>

<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true">

<ImageView
android:id="@+id/logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="@drawable/pic_startpage_logo"/>

<LinearLayout
android:id="@+id/sex_11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/logo"
android:layout_marginTop="10dip"
android:orientation="horizontal">

<Button
android:id="@+id/boy_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/bt_man_up"/>

<Button
android:id="@+id/girl_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/girl_bg"/>
</LinearLayout>

<Button android:id="@+id/gift"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/sex_11"
android:layout_marginTop="10dip"
android:background="@drawable/gift_bg"/>
<Button
android:id="@+id/more"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/gift"
android:layout_marginTop="10dip"
android:background="@drawable/more_bg"
/>



</RelativeLayout>
2，声音部分 soundutil 很重要要写好。

package com.example.test.util;

import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;
import com.example.*;
import com.example.test.R;
import com.example.test.R.raw;

public class SoundUnits {

private static SoundUnits instance;

private SoundPool soundPool;

private int boyResId,girlResId,succeedResId;

private SoundUnits(Context context){

soundPool = new SoundPool(10,AudioManager.STREAM_MUSIC,0);
//boy,girl,succeedde 音频资料
boyResId = soundPool.load(context,R.raw.boy, 1);
girlResId = soundPool.load(context, R.raw.girl, 1);
succeedResId = soundPool.load(context, R.raw.save_succeed, 1);

}

//Java语言的关键字，当它用来修饰一个方法或者一个代码块的时候，能够保证在同一时刻最多只有一个线程执行该段代码。
public static synchronized SoundUnits getInstance(Context context){
if(instance == null){
instance = new SoundUnits(context);

}
return instance;
}

public void playBoySound(){
soundPool.play(boyResId,1.0f,1.0f,5,0,1.0f);
}

public void playGirlSound(){
soundPool.play(girlResId, 1.0f, 1.0f, 5, 0, 1.0f);
}

public void playSucceedSound(){
soundPool.play(succeedResId, 1.0f, 1.0f, 5, 0, 1.0f);
}

public void release(){
soundPool.release();
soundPool = null;
instance = null;
}

}

3，事件监听图片变化和声音变化

package com.example.test;

import com.example.test.util.SoundUnits;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.view.Window;
import android.view.View.OnTouchListener;
import android.widget.Button;
import android.widget.Toast;
//
public class MainActivity extends Activity {
private Button soundBtn;
private Button boybtn;
private Button girlbtn;
private boolean isSoundopen = true;
private SoundUnits soundunits = null;

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
//去掉窗口头表头
requestWindowFeature(Window.FEATURE_NO_TITLE);
//设置这个界面的layout
setContentView(R.layout.activity_main);

soundunits = SoundUnits.getInstance(MainActivity.this);
initButton();
}




private void initButton(){
soundBtn = (Button) findViewById(R.id.sound);
boybtn = (Button) findViewById(R.id.boy_btn);
girlbtn = (Button) findViewById(R.id.girl_btn);
soundBtn.setOnClickListener(new View.OnClickListener(){

public void onClick(View v){

isSoundopen=!isSoundopen;
if(isSoundopen){
soundBtn.setBackgroundResource(R.drawable.bt_homepage_sound_on);

}
else{
soundBtn.setBackgroundResource(R.drawable.bt_homepage_sound_off);
}
}
});

boybtn.setOnTouchListener(new OnTouchListener(){

public boolean onTouch(View v,MotionEvent event){

int action = event.getAction();

switch(action){

case MotionEvent.ACTION_DOWN:

soundunits.playBoySound();
// soundunits.playGirlSound();

Toast.makeText(MainActivity.this, "按钮按下", 0).show();

boybtn.setBackgroundResource(R.drawable.bt_man_down);

break;

case MotionEvent.ACTION_MOVE:

break;

case MotionEvent.ACTION_UP:

Toast.makeText(MainActivity.this, "按钮抬起", 0).show();

boybtn.setBackgroundResource(R.drawable.bt_man_up);

break;
}
return false;
}
}
);
girlbtn.setOnTouchListener(new OnTouchListener(){

public boolean onTouch(View v,MotionEvent event){

int action = event.getAction();

switch(action){

case MotionEvent.ACTION_DOWN:

soundunits.playGirlSound();

Toast.makeText(MainActivity.this, "按钮按下", 0).show();

girlbtn.setBackgroundResource(R.drawable.bt_woman_down);

break;

case MotionEvent.ACTION_MOVE:

break;

case MotionEvent.ACTION_UP:

Toast.makeText(MainActivity.this, "按钮抬起", 0).show();

girlbtn.setBackgroundResource(R.drawable.bt_woman_up);

break;
}
return false;
}
}
);
}


private class MyOnclickListener implements View.OnClickListener{

public void onClick(View v){

}
}

}
问题1，drawable中的boy_bg等等什么意思

问题2，点击声音的图片变化在哪
