在 TextView android 中调整可绘制图像的大小

Question

Wonder how to resize an image inside a TextView xml in a LinearLayout . I read some solution using setCompoundDrawablesWithIntrinsicBounds method, but cannot get it right.

Here is the image:

I want to reduce the size of the logo.

Here is my TextView code:

<TextView  
    android:id="@+id/heading"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableLeft="@drawable/android_logo"
    android:drawableStart="@drawable/android_logo"
    android:gravity="top"
    android:padding="16dp"
    android:singleLine="true"
    android:text="@string/heading"
    android:textSize="20dp"
    android:drawablePadding="5dp"/>

Answer 1

Try:

 android:scaleX="0.7"
 android:scaleY="0.7"

OR

Wrap your resource in a drawable that defines your desired size similar to:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

  <item
      android:drawable="@drawable/icon"
      android:width="@dimen/icon_size"
      android:height="@dimen/icon_size"
      />

</layer-list >

then use it in drawable left.

there is only one solution take image view for the image and resize image but text display image right side. you used below code and i hope your issue solved..

<?xml version="1.0" encoding="utf-8"?>

<ImageView
    android:id="@+id/icon"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:src="@drawable/ic_person" />

<TextView
    android:id="@+id/heading"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="10dp"

    android:gravity="top"
    android:padding="5dp"
    android:singleLine="true"
    android:text="heading"
    android:textSize="20dp"
    app:layout_constraintLeft_toRightOf="@+id/icon" />

Programmatic solution:

You can use drawable.setBounds but it requires pixels rather than dp as parameters.

how to convert: Converting pixels to dp

code:

        Drawable drawable = getDrawable(R.drawable.ic_your_drawable);
        int size = dp2px(this, dpSize);
        if (drawable != null) {
            drawable.setBounds(0, 0, size, size);
        }

        textView.setCompoundDrawables(drawable, drawable, drawable, drawable); // should be (drawable, null, null, null) for you
