Java Can';t重新缩放可缩进按钮
我正在尝试缩小一个可在Java Can';t重新缩放可缩进按钮,java,android,Java,Android,我正在尝试缩小一个可在按钮中使用的绘图。现在,我的按钮中没有显示任何内容: 左边应该有一个抽屉。 这里有什么问题?我所做的和我在这里看到的不同答案中看到的完全一样 XML: 也许这个选项会有所帮助 <Button android:id="@+id/fnbButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@d
按钮中使用的绘图。现在,我的按钮中没有显示任何内容:
左边应该有一个抽屉。
这里有什么问题?我所做的和我在这里看到的不同答案中看到的完全一样
XML:
也许这个选项会有所帮助
<Button
android:id="@+id/fnbButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/rounded_button_blue"
android:padding="5dp"
android:text="@string/fnb_button"
android:textAllCaps="false"
android:textColor="@color/white"
app:layout_constraintBaseline_toBaselineOf="@id/otherButton"
app:layout_constraintEnd_toEndOf="parent" />
试试这个
private void useScaledDrawableLeft(Button buttonView, float scale, @DrawableRes int imageResource) {
Resources res = getResources();
BitmapDrawable bd = (BitmapDrawable) res.getDrawable(imageResource);
Bitmap b = Bitmap.createScaledBitmap(bd.getBitmap(),
(int) (bd.getIntrinsicHeight() * scale),
(int) (bd.getIntrinsicWidth() * scale),
false);
BitmapDrawable scaleDrawable = new BitmapDrawable(b);
buttonView.setCompoundDrawablesWithIntrinsicBounds(scaleDrawable, null, null, null);
}
我最终做了这样的事:
Drawable drawable = getResources().getDrawable(R.drawable.cutlerywhite);
ScaleDrawable sd = new ScaleDrawable(drawable, Gravity.CENTER, iconScale, iconScale);
Drawable d1 = sd.getDrawable();
d1.setLevel(1);
sd.setLevel(1);
fnbButton.setCompoundDrawablesWithIntrinsicBounds(sd, null, null, null);
你能显示你的餐具白色和按钮布局的代码吗?为按钮添加了xml。餐具白色只是一个图像。你建议我在哪里调用此功能?
Drawable drawable = getResources().getDrawable(R.drawable.cutlerywhite);
ScaleDrawable sd = new ScaleDrawable(drawable, Gravity.CENTER, iconScale, iconScale);
Drawable d1 = sd.getDrawable();
d1.setLevel(1);
sd.setLevel(1);
fnbButton.setCompoundDrawablesWithIntrinsicBounds(sd, null, null, null);
Drawable drawableFnb = getResources().getDrawable(R.drawable.cutlerywhite);
Drawable drawableSunbed = getResources().getDrawable(R.drawable.logowhite);
ScaleDrawable sdFnb = new ScaleDrawable(drawableFnb, Gravity.LEFT, 1, 1);
ScaleDrawable sdSunbed = new ScaleDrawable(drawableSunbed, Gravity.LEFT, 1, 1);
Drawable d1 = sdFnb.getDrawable();
Drawable d2 = sdSunbed.getDrawable();
Dims fnbDims = getIconDims(drawableFnb);
Dims sunbedDims = getIconDims(drawableSunbed);
d1.setBounds(0, 0, fnbDims.getWidth(), fnbDims.getHeight());
d2.setBounds(0, 0, sunbedDims.getWidth(), sunbedDims.getHeight());
fnbButton.setCompoundDrawables(d1, null, null, null);
sunbedButton.setCompoundDrawables(d2, null, null, null);
