Java 如何采取行动？单击延迟

我有行动的代码。有什么可以使我石化来解决这个问题吗。我想增加行动的延迟

private void performSmsAppMessage(final AccessibilityNodeInfo rootNode) {

    AccessibilityNodeInfo textNode = getNodeInfo(rootNode, waTextID);
    if (textNode == null || sendBlaster == null) return;
    Bundle textBundle = new Bundle();
    textBundle.putCharSequence(AccessibilityNodeInfo.ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE, sendBlaster);
    textNode.performAction(AccessibilityNodeInfo.ACTION_SET_TEXT, textBundle);
    AccessibilityNodeInfo buttonSend = getNodeInfo(rootNode, waSendID);

    if (buttonSend == null) return;
    buttonSend.performAction(AccessibilityNodeInfo.ACTION_CLICK);
    AccessibilityNodeInfo backButton = getNodeInfo(rootNode, waBackID);

    if (backButton != null) backButton.performAction(AccessibilityNodeInfo.ACTION_CLICK);

}

如果要延迟任何操作，请尝试以下操作：

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //put you action here
    }
}, 1300); //milliseconds to delay, in this case 1.3 seconds

单击此代码按钮Send.performAction（AccessibilityNodeInfo.ACTION）；
