UiAutomator: How to achieve a paste action using uiautomator?

I need to have non-ASCII character (like chinese character) inputted in EditText, I found the UiObject.setText() method can not do this work.

So I get a method: copy the character to the clipboard, then paste it to the EditText. Now I have achieved the copy work, but don't know how to achieve the paste action using code.

I searched on the web, and find paste action can be achieved using hotkeys: "menu" + "v"

so I go to the UiDevice api, and find a method: pressKeycode(), but it can only press one key code a time.

Does anyone knows how to press "menu" and "v" at same time using uiautomator or there is some original code to achieve this?

Thanks very much!

Solution

I have resolved this issue. see code below:

public class MyTest  extends TestCase{

    /**
    * Paste text to an EditText feild which is currentlly get focused.
    *
    * @param: text the text(Non-ASCII) you want to paste into EditText feild. 
    */
    IClipboard clipboard = IClipboard.Stub.asInterface(ServiceManager.getService(Context.CLIPBOARD_SERVICE));
    IInputManager iInputManager = IInputManager.Stub.asInterface(ServiceManager.getService(Context.INPUT_SERVICE)); 
    private void pastText(String text) throws UiObjectNotFoundException{
        try {
            //copy the text to clipboard.
            clipboard.setPrimaryClip(ClipData.newPlainText("NonASCII", text), text);   

            //inject event: press Menu + V         
            iInputManager.injectInputEvent(
                new KeyEvent(android.os.SystemClock.uptimeMillis(), 
                             android.os.SystemClock.uptimeMillis(), 
                             KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MENU, 0),1); 
            iInputManager.injectInputEvent(
                new KeyEvent(android.os.SystemClock.uptimeMillis(), 
                             android.os.SystemClock.uptimeMillis(), 
                             KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_V, 0),1);              
            iInputManager.injectInputEvent(
                new KeyEvent(android.os.SystemClock.uptimeMillis(), 
                             android.os.SystemClock.uptimeMillis(), 
                             KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MENU, 0),1);
            iInputManager.injectInputEvent(
                new KeyEvent(android.os.SystemClock.uptimeMillis(), 
                             android.os.SystemClock.uptimeMillis(), 
                             KeyEvent.ACTION_UP, KeyEvent.KEYCODE_V, 0),1);              

            //After "Menu"+"V" pressed, A "Menu" will show if exist in current Activicy.
            //Then press menu again, to make it down just for bug fixing.
            sleep(300);
            iInputManager.injectInputEvent(
                new KeyEvent(android.os.SystemClock.uptimeMillis(), 
                             android.os.SystemClock.uptimeMillis(), 
                             KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MENU, 0),1); 
            iInputManager.injectInputEvent(
                new KeyEvent(android.os.SystemClock.uptimeMillis(), 
                             android.os.SystemClock.uptimeMillis(), 
                             KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MENU, 0),1);

        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }

}

Thanks.
