Example 6 with ScaleGestureDetector

use of android.view.ScaleGestureDetector in project TouchImageView by MikeOrtiz.

the class TouchImageView method sharedConstructing.

private void sharedConstructing(Context context) {
    super.setClickable(true);
    this.context = context;
    mScaleDetector = new ScaleGestureDetector(context, new ScaleListener());
    mGestureDetector = new GestureDetector(context, new GestureListener());
    matrix = new Matrix();
    prevMatrix = new Matrix();
    m = new float[9];
    normalizedScale = 1;
    if (mScaleType == null) {
        mScaleType = ScaleType.FIT_CENTER;
    }
    minScale = 1;
    maxScale = 3;
    superMinScale = SUPER_MIN_MULTIPLIER * minScale;
    superMaxScale = SUPER_MAX_MULTIPLIER * maxScale;

    setState(State.NONE);
    onDrawReady = false;
    super.setOnTouchListener(new PrivateOnTouchListener());
}

Example 7 with ScaleGestureDetector

use of android.view.ScaleGestureDetector in project Signal-Android by WhisperSystems.

the class MotionView method init.

private void init(@NonNull Context context, @Nullable AttributeSet attrs) {

    selectedLayerPaint = new Paint();
    selectedLayerPaint.setAlpha((int) (255 * Constants.SELECTED_LAYER_ALPHA));
    selectedLayerPaint.setAntiAlias(true);
    this.editText = new EditText(context, attrs);
    ViewCompat.setAlpha(this.editText, 0);
    this.editText.setLayoutParams(new LayoutParams(1, 1, Gravity.TOP | Gravity.LEFT));
    this.editText.setClickable(false);
    this.editText.setBackgroundColor(Color.TRANSPARENT);
    this.editText.setTextSize(TypedValue.COMPLEX_UNIT_SP, 1);
    this.editText.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
    this.addView(editText);
    this.editText.clearFocus();
    this.editText.addTextChangedListener(this);
    // init listeners
    this.scaleGestureDetector = new ScaleGestureDetector(context, new ScaleListener());
    this.rotateGestureDetector = new RotateGestureDetector(context, new RotateListener());
    this.moveGestureDetector = new MoveGestureDetector(context, new MoveListener());
    this.gestureDetectorCompat = new GestureDetectorCompat(context, new TapsListener());
    setOnTouchListener(onTouchListener);
    updateUI();
}
