安卓获取res下的资源文件：string字符串、color颜色、dimen尺寸、array数组、drawable图片和xml、anim/animator动画、raw媒体、assets资源

public void getresource() {
Resources myResources = getResources();   //获取资源表实例

CharSequence mytext = myResources.getText(R.string.str1);   //获取字符串，string.xml
textView1.setText(mytext);

int mycolor= myResources.getColor(R.color.red);  //获取颜色,color.xml
textView1.setTextColor(mycolor);

float mydimen=myResources.getDimension(R.dimen.dimen2);  //获取尺寸，dimen.xml
textView1.setTextSize(mydimen);

String[] mystrarray=myResources.getStringArray(R.array.str_array);  //获取字符串数组，array.xml
Log.v("资源字符串数组", mystrarray.toString());

int[] myintarray=myResources.getIntArray(R.array.int_array);  //获取整型数组,array.xml
Log.v("资源整型数组", myintarray.toString());

}

//系统资源的使用
public void get_system_resource() {

Log.v("系统字符串", mytext.toString());
}

myAnimator1.setTarget(button1);  //动画绑定控件

imageView1.setBackgroundResource(R.drawable.anim3);   //获取逐帧动画，drawable文件夹下，动画绑定控件
AnimationDrawable myanimation3 = (AnimationDrawable) imageView1.getBackground();    //获取对动画的引用
myanimation3.start();  //启动逐帧动画
}

//音乐文件

//视频文件（3gp,wmv,mp4），通过uri

//文本文件
