如果你的EditText不清楚:

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

or

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

这个问题已经很老了，但我认为如果你想使用Android上最新发布的DataBinding工具，有这个答案可能会很有用，只需在XML中设置这个:

<data>
    <variable name="stringValue" type="String"/>
</data>
...
<EditText
        ...
        android:text="@={stringValue}"
        android:selection="@{stringValue.length()}"
        ...
/>

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

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())
        }
    }
}

/**
 * Set cursor to end of text in edittext when user clicks Next on Keyboard.
 */
View.OnFocusChangeListener onFocusChangeListener = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean b) {
        if (b) {
            ((EditText) view).setSelection(((EditText) view).getText().length());
        }
    }
};

mEditFirstName.setOnFocusChangeListener(onFocusChangeListener); 
mEditLastName.setOnFocusChangeListener(onFocusChangeListener);

这对我很有用!

类似于@Anh Duy的回答，但对我没用。我还需要光标移动到最后，只有当用户点击编辑文本，仍然能够选择光标的位置之后，这是唯一的代码，已经为我工作

boolean textFocus = false; //define somewhere globally in the class

//in onFinishInflate() or somewhere
editText.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {

        editText.onTouchEvent(event);

        if(!textFocus) {
            editText.setSelection(editText.getText().length());
            textFocus = true;
        }

        return true;
    }
});

editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        textFocus = false;
    }
});
