Usage

From source file:Main.java

protected static Bitmap creatCodeBitmap(String contents, int width, int height, Context context) {
    TextView tv = new TextView(context);
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    tv.setLayoutParams(layoutParams);//from  ww  w  .  j a v a 2s.c o m
    tv.setText(contents);
    tv.setHeight(height);
    tv.setGravity(Gravity.CENTER_HORIZONTAL);
    tv.setWidth(width);
    tv.setDrawingCacheEnabled(true);
    tv.setTextColor(Color.BLACK);
    tv.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
            View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
    tv.layout(0, 0, tv.getMeasuredWidth(), tv.getMeasuredHeight());

    tv.buildDrawingCache();
    Bitmap bitmapCode = tv.getDrawingCache();
