[java] 프로그래밍 방식으로 드로어 블 크기 설정

Question 1

이미지 (아이콘)의 크기는 거의 같지만 버튼의 높이를 동일하게 유지하려면 크기를 조정해야합니다.

어떻게해야합니까?

Button button = new Button(this);
button.setText(apiEventObject.getTitle());
button.setOnClickListener(listener);

/*
 * set clickable id of button to actual event id
 */
int id = Integer.parseInt(apiEventObject.getId());
button.setId(id);

button.setLayoutParams(new LayoutParams(
        android.view.ViewGroup.LayoutParams.FILL_PARENT,
        android.view.ViewGroup.LayoutParams.WRAP_CONTENT));

Drawable drawable = LoadImageFromWebOperations(apiSizeObject.getSmall());
//?resize drawable here? drawable.setBounds(50, 50, 50, 50);
button.setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null);

Question 2

이 setBounds()방법은 모든 유형의 컨테이너에서 작동하지 않습니다 ( ImageView그러나 일부 컨테이너에서는 작동했습니다 ).

드로어 블 자체의 크기를 조정하려면 아래 방법을 시도하십시오.

// Read your drawable from somewhere
Drawable dr = getResources().getDrawable(R.drawable.somedrawable);
Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();
// Scale it to 50 x 50
Drawable d = new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(bitmap, 50, 50, true));
// Set your new, scaled drawable "d"

Question 3

로 크기 지정 setBounds(), 즉 50×50 크기 사용

drawable.setBounds(0, 0, 50, 50);

public void setBounds (int left, int top, int right, int bottom)

Question 4

.setBounds (..)를 적용하기 전에 현재 Drawable을 ScaleDrawable로 변환 해보십시오.

drawable = new ScaleDrawable(drawable, 0, width, height).getDrawable();

그 후

drawable.setBounds(0, 0, width, height);

작동 할 것이다

Question 5

setBounds () 메서드가 예상대로 비트 맵 드로어 블에서 작동하지 않는 이유를 파헤칠 시간이 없었지만 setBounds가해야 할 일을하기 위해 @ androbean-studio 솔루션을 약간 조정했습니다 …

/**
 * Created by ceph3us on 23.05.17.
 * file belong to pl.ceph3us.base.android.drawables
 * this class wraps drawable and forwards draw canvas
 * on it wrapped instance by using its defined bounds
 */
public class WrappedDrawable extends Drawable {

    private final Drawable _drawable;
    protected Drawable getDrawable() {
        return _drawable;
    }

    public WrappedDrawable(Drawable drawable) {
        super();
        _drawable = drawable;
    }

    @Override
    public void setBounds(int left, int top, int right, int bottom) {
        //update bounds to get correctly
        super.setBounds(left, top, right, bottom);
        Drawable drawable = getDrawable();
        if (drawable != null) {
            drawable.setBounds(left, top, right, bottom);
        }
    }

    @Override
    public void setAlpha(int alpha) {
        Drawable drawable = getDrawable();
        if (drawable != null) {
            drawable.setAlpha(alpha);
        }
    }

    @Override
    public void setColorFilter(ColorFilter colorFilter) {
        Drawable drawable = getDrawable();
        if (drawable != null) {
            drawable.setColorFilter(colorFilter);
        }
    }

    @Override
    public int getOpacity() {
        Drawable drawable = getDrawable();
        return drawable != null
                ? drawable.getOpacity()
                : PixelFormat.UNKNOWN;
    }

    @Override
    public void draw(Canvas canvas) {
        Drawable drawable = getDrawable();
        if (drawable != null) {
            drawable.draw(canvas);
        }
    }

    @Override
    public int getIntrinsicWidth() {
        Drawable drawable = getDrawable();
        return drawable != null
                ? drawable.getBounds().width()
                : 0;
    }

    @Override
    public int getIntrinsicHeight() {
        Drawable drawable = getDrawable();
        return drawable != null ?
                drawable.getBounds().height()
                : 0;
    }
}

용법:

// get huge drawable 
final Drawable drawable = resources.getDrawable(R.drawable.g_logo);
// create our wrapper           
WrappedDrawable wrappedDrawable = new WrappedDrawable(drawable);
// set bounds on wrapper 
wrappedDrawable.setBounds(0,0,32,32);
// use wrapped drawable 
Button.setCompoundDrawablesWithIntrinsicBounds(wrappedDrawable ,null, null, null);

Question 6

쓰다

textView.setCompoundDrawablesWithIntrinsicBounds()

minSdkVersion은 build.gradle에서 17이어야합니다.

    defaultConfig {
    applicationId "com.example..."
    minSdkVersion 17
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}

드로어 블 크기를 변경하려면 :

    TextView v = (TextView)findViewById(email);
    Drawable dr = getResources().getDrawable(R.drawable.signup_mail);
    Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();
    Drawable d = new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(bitmap, 80, 80, true));

    //setCompoundDrawablesWithIntrinsicBounds (image to left, top, right, bottom)
    v.setCompoundDrawablesWithIntrinsicBounds(d,null,null,null);

Question 7

포스트 방법을 사용하여 원하는 효과를 얻으십시오.

{your view}.post(new Runnable()
    {
        @Override
        public void run()
        {
            Drawable image = context.getResources().getDrawable({drawable image resource id});
            image.setBounds(0, 0, {width amount in pixels}, {height amount in pixels});
            {your view}.setCompoundDrawables(image, null, null, null);
        }
    });

Question 8

아마 조금 늦었을 것입니다. 그러나 여기에 모든 상황에서 마침내 나를 위해 일한 솔루션이 있습니다.

아이디어는 고정 된 크기의 사용자 정의 드로어 블을 만들고 드로잉 작업을 원본 드로어 블에 전달하는 것입니다.

Drawable icon = new ColorDrawable(){
        Drawable iconOrig = resolveInfo.loadIcon(packageManager);

        @Override
        public void setBounds(int left, int top, int right, int bottom){
            super.setBounds(left, top, right, bottom);//This is needed so that getBounds on this class would work correctly.
            iconOrig.setBounds(left, top, right, bottom);
        }

        @Override
        public void draw(Canvas canvas){
            iconOrig.draw(canvas);
        }

        @Override
        public int getIntrinsicWidth(){
            return  mPlatform.dp2px(30);
        }

        @Override
        public int getIntrinsicHeight(){
            return  mPlatform.dp2px(30);
        }
    };
