editText.accessibilityDelegate = object : View.AccessibilityDelegate() {
    override fun sendAccessibilityEvent(host: View?, eventType: Int) {
        super.sendAccessibilityEvent(host, eventType)
        if (eventType == TYPE_VIEW_TEXT_SELECTION_CHANGED) {
            editText.setSelection(editText.length())
        }
    }
}

这个方法很安全:

    editText.setText("");
    if (!TextUtils.isEmpty(text)) {
        editText.append(text);
    }

您应该能够在EditText的方法setSelection()的帮助下实现这一点，请参阅这里

你也可以像这样把光标放在EditText视图中文本的末尾:

EditText et = (EditText)findViewById(R.id.textview);
int textLength = et.getText().length();
et.setSelection(textLength, textLength);

试试这个:

<EditText
    android:id="@+id/edt_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    android:cursorVisible="true"/>

在你的代码中:

EditText editText = findViewById(R.id.editText);
editText.setSelection(editText.getText().length()); // Set cursor end point

editText.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        editText.setSelection(editText.getText().length());
        return false;
    }
});
