这是

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

我认为这可以达到你想要的效果。

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

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())
        }
    }
}

科特林：

将光标设置到起始位置:

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(0)

将光标设置到EditText的末尾:

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(editText.text.length)

下面的Code是将光标放在第二个字符之后:

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(2)

JAVA:

将光标设置到起始位置:

 EditText editText = (EditText)findViewById(R.id.edittext_id);
 editText.setSelection(0);

将光标设置到EditText的末尾:

EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(editText.getText().length());

下面的Code是将光标放在第二个字符之后:

EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(2);

这个方法很安全:

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