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);

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())
        }
    }
}

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

我认为这可以达到你想要的效果。

 Editable etext = mSubjectTextEditor.getText();
 Selection.setSelection(etext, etext.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);

如果你的EditText不清楚:

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

or

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