惯用的getResources()系列

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);}
