Android学习笔记(四)
曾国藩:内断于心,自为主持

前一阶段的学习因为种种原因有些耽误了,近一段时间工作不太忙,希望可以继续坚持,坚持,在坚持一下。前一阶段主要是学习的mars老师的视频,现在结合视频和最近看的一些书籍,进一步进行一些学习:

1、在android引用图片和声音文件可以通过直接拷贝到res/文件夹下相应的文件夹内,Eclipse可以自动进行匹配生成xml资源文件。使用图片文件可以使用XML配置ImageView控件的方法,也可以使用(在Activity当中):

ImageView myView=new ImageView(this);

myView.setImageBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.img));//img
为图片文件名称

this.setContentView(myView);

2、使用声音文件同样可以进行拷贝,文件夹可以自定义,播放也可以有两种方法:

一是使用MediaPlayer类方法,在Activity中

声明 MediaPlayer myPlayer;

在OnCreate方法中

myPlayer=MediaPlayer.Create(this,R.arw.sound);

myPlayer.start();

二是使用soundpool方法类,其方法有点复杂,在后面的mars的案例教学中再深入学习吧。

3、Androidmanifest.xml是对整体程序的设置,其中有一项Manifest。Permission中设置应用程序的权限,在</manifest>之前设置就可以。
