android:ellipsize, android:singleLine -> Java Code

android:ellipsize="end"
android:singleLine="true"

textview.setEllipsize(TruncateAt.END);
textview.setSingleLine(true);

xml -> java code 변경

android:layout_gravity="center_horizontal"

=> LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL)

layout width, hieght 값 설정 방법 - Java Code

1. width값에 해당하는 dip값 integer형 선언
2. float 형 변수 선언
3. layout 세팅

int width_dip = 180;

float width_layout = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, width_dip, r.getDisplayMetrics());

setLayoutParams( new RelativeLayout.LayoutParams( (int)width_layout , LayoutParams.FILL_PARENT) );

height 값도 마찬가지...

TextView 한글의 Bold 처리

text.setText("한글 볼드 테스트"); 
text.setPaintFlags(text.getPaintFlags() | Paint.FAKE_BOLD_TEXT_FLAG);

스크롤바 없애기

android:scrollbars="@null"

단말의 DIP, WIDTH, HEIGHT 값 구하기

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);

density = displaymetrics.densityDpi;
width = displaymetrics.widthPixels;
height = displaymetrics.heightPixels;

Bitmap <--> Drawable

[Bitmap to Drawable]
BitmapDrawable bitmapDrawable = (BitmapDrawable)bitmap;
Drawable drawable = (Drawable)bitmapDrawable;

Bitmap bitmap = new Bitmap (...);
Drawable drawable = new BitmapDrawable(bitmap);

[Drawable to Bitmap] 
Bitmap bitmap = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
d.setBounds(0, 0, w, h);
d.draw(canvas);
