How can Android achieve automatic adjustment of font size?

In Android, you can achieve automatic font size adjustment by setting the properties of a TextView. The specific steps are as follows:

1. automatically adjust the text size uniformly

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:autoSizeTextType="uniform"
    android:text="Hello World!" />

1. Set the text size to adjust uniformly according to the configuration.

TextView textView = findViewById(R.id.textView);
textView.setAutoSizeTextTypeUniformWithConfiguration(
    12, // 最小字体大小（以sp为单位）
    24, // 最大字体大小（以sp为单位）
    2, // 字体大小增量
    TypedValue.COMPLEX_UNIT_SP // 字体大小单位
);

By following the steps above, the font size will automatically adjust to fit the width of the TextView when its content exceeds the width.
