使EditText提示全部大写

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="ENTER YOUR TEXT HERE" />

EditText editText = findViewById(R.id.editText);
editText.setHint("enter your text here".toUpperCase());

val editText = findViewById<EditText>(R.id.editText)
editText.hint = "enter your text here".toUpperCase()

editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}

    @Override
    public void afterTextChanged(Editable s) {
        editText.setHint(editText.getHint().toString().toUpperCase());
    }
});

editText.addTextChangedListener(object : TextWatcher {
    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {}

    override fun afterTextChanged(s: Editable?) {
        editText.hint = editText.hint.toString().toUpperCase()
    }
})
