我正在尝试使用缩放,旋转和移动属性在图像上添加文本。我通过将文本转换为图像部分实现了这一点,但我想通过仅使用textview来做同样的事情。

Try This
public class simpleOnScaleGestureListener extends SimpleOnScaleGestureListener {
@Override
public boolean onScale(ScaleGestureDetector detector) {
float size = codedText.getTextSize();
float factor = detector.getScaleFactor();
int increase = 0;
if(factor > 1.0f)
increase = 2;
else if(factor < 1.0f)
increase = -2;
size += increase;
textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, size);
try {
Thread.sleep(200);
} catch (InterruptedException e) {
e.printStackTrace();
}
//remembering the favourable text size
Editor edit = sp.edit();
edit.putFloat("TXTSIZE", size);
edit.commit();
return true;
}
}
