是否在不使用xml的情况下更改edittext光标的颜色和大小？

EditText editText = findViewById(R.id.editText);
try {
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    f.set(editText, R.drawable.custom_cursor); // 将R.drawable.custom_cursor替换为你自定义的光标资源
} catch (Exception e) {
    e.printStackTrace();
}

EditText editText = findViewById(R.id.editText);
try {
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    Drawable cursor = ContextCompat.getDrawable(this, R.drawable.custom_cursor); // 将R.drawable.custom_cursor替换为你自定义的光标资源
    cursor.setBounds(0, 0, cursor.getIntrinsicWidth(), yourDesiredHeight); // 将yourDesiredHeight替换为你想要的光标高度
    Drawable[] drawables = {cursor, cursor};
    f.set(editText, drawables);
} catch (Exception e) {
    e.printStackTrace();
}
