这是

Editable etext = edittext.getText();
Selection.setSelection(etext,edittext.getText().toString().length());

如果您想将光标放置在EditText视图中文本的末尾

 EditText rename;
 String title = "title_goes_here";
 int counts = (int) title.length();
 rename.setSelection(counts);
 rename.setText(title);

有一个名为append for ediitext的函数，它将字符串值追加到当前edittext值，并将光标放在值的末尾。 你可以将字符串值本身作为当前编辑文本值，并调用append();

myedittext.append("current_this_edittext_string"); 

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())
        }
    }
}

如果你的EditText不清楚:

editText.setText("");
editText.append("New text");

or

editText.setText(null);
editText.append("New text");

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);
