常用的getResources()系列

 

以例子形式说明如何提取资源文件设置view或sting：

private Context ctx;

TextView mText = (TextView)findViewById(R.id.text);
ImageView mImage = (ImageView)findViewById(R.id.image); 
TextView[] mTextViews;
String[] arrays;
String str; 

 

(1)R.dimen.xxx

mText.setTextSize(TypedValue.COMPLEX_UNIT_PX, 
			ctx.getResources().getDimensionPixelSize(R.dimen.xxx));

 

(2)R.color.xxx

mText.setTextColor(ctx.getResources().getColorStateList(R.color.xxx));
mText.setTextColor(ctx.getResources().getColor(R .color.xxx));

 

(3)R.drawable.xxx

mImage.setImageDrawable(ctx.getResources().getDrawable(R.drawable.xxx))

 

(4)R.raw.xxx

InputStream is = ctx.getResources().openRawResource(R.raw.xxx); 

 

(5)R.array.xxx

arrays = getResources().getStringArray(R.array.xxx);

 

(6)R.string.xxx

str = getResources().getString(R.string.xxx)

 

 (7)getIdentifier
用于view的id名称具有相同的部分,如前缀xxx,利用后面的数字进行区别的view

mTextViews = new TextView[LEN]
for (int i = 0; i < mTextViews.length; i++) {
int resId = getResources().getIdentifier("xxx" + i, "id",packageName);
		mTextViews[i] = (TextView) findViewById(resId);}
