推荐答案

您可以使用<一个href="http://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.html#ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE"相对=nofollow> ACTION_SET_TEXT 为> =机器人21。 下面是它的例子：

You can use ACTION_SET_TEXT for >= android 21. Here is the example of it:

AccessibilityNodeInfo source = event.getSource();
if (source != null & event.getClassName().equals("android.widget.EditText")) {
    Bundle arguments = new Bundle();
    arguments.putCharSequence(AccessibilityNodeInfo
            .ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE, "android");
    source.performAction(AccessibilityNodeInfo.ACTION_SET_TEXT, arguments);
}
