Текст растягивается на другом экране в моем пользовательском представлении после настройки размера текста в dp android
Я пытаюсь создать текстовую наклейку в android. Я создаю текстовую наклейку на одном из своих телефонов, а затем сохраняю размер текста в DP. Затем на другом телефоне я загружаю тот же текст с тем же DP и конвертирую значение DP в пиксель. Затем вызов метода
TextPaint.setTextSize(pixelValue)
Но вывод на обоих телефонах разный. Я также пробовал заменить DP на SP, но, похоже, это не решение.
Еще одна вещь: я определяю ширину и высоту своего представления на основе высоты ширины (res), которую можно рисовать.
Вот код этого чертежа
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent" />
<size android:width="200dp" android:height="50dp" />
</shape>
Но это не похоже на проблему, поскольку значения указаны в DP в файле с возможностью рисования.
Вот конструктор текстовой наклейки.
public DynamicTextSticker(@NonNull Context context, @Nullable Drawable drawable, String text) {
this.context = context;
this.drawable = drawable;
if (drawable == null) {
this.drawable = ContextCompat.getDrawable(context, R.drawable.sticker_transparent_background);
}
textPaint = new TextPaint(TextPaint.ANTI_ALIAS_FLAG);
minTextSizePixels = DensityUtils.px2dp(context, 6);
maxTextSizePixels = DensityUtils.px2dp(context, 32);
alignment = Layout.Alignment.ALIGN_CENTER;
textPaint.setTextSize(maxTextSizePixels);
realBounds = new Rect(0, 0, getWidth(), getHeight());
textRect = new Rect(0, 0, getWidth(), getHeight());
}
draw method
@Override public void draw(@NonNull Canvas canvas) {
Matrix matrix = getMatrix();
canvas.save();
canvas.concat(matrix);
if (drawable != null) {
drawable.setBounds(realBounds);
drawable.draw(canvas);
}
canvas.restore();
canvas.save();
canvas.concat(matrix);
if (textRect.width() == getWidth()) {
int dy = getHeight() / 2 - staticLayout.getHeight() / 2;
// center vertical
canvas.translate(0, dy);
} else {
int dx = textRect.left;
int dy = textRect.top + textRect.height() / 2 - staticLayout.getHeight() / 2;
canvas.translate(dx, dy);
}
staticLayout.draw(canvas);
canvas.restore();
}
here is the resize method where the static layout is initialized
final int availableHeightPixels = textRect.height();
final int availableWidthPixels = textRect.width();
final CharSequence text = getText();
// Safety check
// (Do not resize if the view does not have dimensions or if there is no text)
if (text == null
|| text.length() <= 0
|| availableHeightPixels <= 0
|| availableWidthPixels <= 0
|| maxTextSizePixels <= 0) {
return this;
}
float targetTextSizePixels = maxTextSizePixels;
int targetTextHeightPixels =
getTextHeightPixels(text, availableWidthPixels, targetTextSizePixels);
// Until we either fit within our TextView
// or we have reached our minimum text size,
// incrementally try smaller sizes
while (targetTextHeightPixels > availableHeightPixels
&& targetTextSizePixels > minTextSizePixels) {
targetTextSizePixels = Math.max(targetTextSizePixels - 2, minTextSizePixels);
targetTextHeightPixels =
getTextHeightPixels(text, availableWidthPixels, targetTextSizePixels);
}
// If we have reached our minimum text size and the text still doesn't fit,
// append an ellipsis
// (NOTE: Auto-ellipsize doesn't work hence why we have to do it here)
if (targetTextSizePixels == minTextSizePixels
&& targetTextHeightPixels > availableHeightPixels) {
// Make a copy of the original TextPaint object for measuring
TextPaint textPaintCopy = new TextPaint(textPaint);
textPaintCopy.setTextSize(targetTextSizePixels);
// Measure using a StaticLayout instance
StaticLayout staticLayout =
new StaticLayout(text, textPaintCopy, availableWidthPixels, Layout.Alignment.ALIGN_NORMAL,
lineSpacingMultiplier, lineSpacingExtra, false);
// Check that we have a least one line of rendered text
if (staticLayout.getLineCount() > 0) {
// Since the line at the specific vertical position would be cut off,
// we must trim up to the previous line and add an ellipsis
int lastLine = staticLayout.getLineForVertical(availableHeightPixels) - 1;
if (lastLine >= 0) {
int startOffset = staticLayout.getLineStart(lastLine);
int endOffset = staticLayout.getLineEnd(lastLine);
float lineWidthPixels = staticLayout.getLineWidth(lastLine);
float ellipseWidth = textPaintCopy.measureText(mEllipsis);
// Trim characters off until we have enough room to draw the ellipsis
while (availableWidthPixels < lineWidthPixels + ellipseWidth) {
endOffset--;
lineWidthPixels =
textPaintCopy.measureText(text.subSequence(startOffset, endOffset + 1).toString());
}
setText(text.subSequence(0, endOffset) + mEllipsis);
}
}
}
textPaint.setTextSize(targetTextSizePixels);
this.targetTextSizePixel = targetTextSizePixels;
staticLayout =
new StaticLayout(this.text, textPaint, textRect.width(), alignment, lineSpacingMultiplier,
lineSpacingExtra, true);
return this;
here is the getWidth and getHeight method
@Override public int getWidth() {
return drawable.getIntrinsicWidth();
}
@Override public int getHeight() {
return drawable.getIntrinsicHeight();
}
I tried several ways but none of them worked for me.
I think the problem is not with text size. but the problem might be with drawable. But I don't know what possibly could go wrong with that, as I have used DP unit everywhere.
**If i forget to add any code please tell me I will attach it as well**
I am new to android so I am not sure the reason behind this problem.
Thanks for your help.
