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);

tile background 방법

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/MainLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/backrepeat">


/res/drawable/backrepeat.xml 생성한다.


<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/back" 
android:tileMode="repeat" />

스크롤 관련

1. 스크롤 버튼 : setFastScrollEnabled(true)
2. 스크롤 할때만 나타나게 하기 : android:fadeScrollbars="true"
3. 스크롤 이미지 변경

    android:scrollbarTrackVertical="@drawable/..."
    android:scrollbarTrackHorizontal="@drawable/..."

TextView의 텍스트 간격 넓히기(자간 간격)

android:lineSpacingExtra  : 라인의 간격을 더하기로 계산 Text의 height + LineSpacing
android:lineSpacingMultiplier : 라인의 간격을 곱하기로 계산 Text의 height * LineSpacing

[android:lineSpacingExtra]


Extra spacing between lines of text.

Must be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), mm (millimeters).

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol lineSpacingExtra.

• setLineSpacing(float,float)

[android:lineSpacingMultiplier]


Extra spacing between lines of text, as a multiplier.

Must be a floating point value, such as "1.2".

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol lineSpacingMultiplier.
