java - 如何在 textInputEditText 中添加图像 (X) 并清除 fragment 中的字段？

Question

我有这个奇怪的代码。老开发人员创建了一个FRAGMENT，所有组件都是用JAVA代码创建的，而不是用XML创建的。
我不知道如何在 EditText 中放置图像，一旦我输入内容，就会出现一个按钮 (x)
如何通过Java代码在textInputEditText中添加图像(X)并清除该字段？ 硬代码

Answer 1

EditText 文本 = (EditText)findViewById(R.id.text);text.setCompoundDrawables(null, null, getResources().getDrawable(R.drawable.your_image), null);参数是图像的方向。
