Espresso - typeText not working

问题:

I'm trying to type some text inside an EditText:

    public void testSearch() {
          onView(withId(R.id.titleInput)).perform(typeText("Engineer"));
          onView(withId(R.id.titleInput)).check(matches(withText("Engineer")));
    }

I see the EditText is getting focus, but nothing happens. No text is typed.
I tried this on a phone and an emulator - same result.

回答1:

Looks like I figured out the issue. It had to do with hardware vs software keyboard.

For Emulators:

Go to Settings -> Language & Input -> switch the Default Input to Sample Soft Keyboard.

For Phones:

Install a software keyboard from the Play store and switch to it. It appears that the native keyboards of some phones do not work.

It works now.

If the EditText does not has the focus yet, you should click on it first. If this solves your problem, then there is no bug.

onView(withId(R.id.titleInput)).perform(click()).perform(typeText("Engineer"));

Had the same issue using Espresso 2. As a workaround I'm using replaceText instead of typeText.

public void testSearch() {
      onView(withId(R.id.titleInput)).perform(click(), replaceText("Engineer"));
      onView(withId(R.id.titleInput)).check(matches(withText("Engineer")));
}

You can bypass the problem by calling setText on the EditText.

   final EditText titleInput = (EditText) activity.findViewById(R.id.titleInput);
   getInstrumentation().runOnMainSync(new Runnable() {
        public void run() {
            titleInput.setText("Engineer");
        }
    });

回答5:

You can include it with in the code like this,

onView(withId(R.id.titleInput)).perform(click(), replaceText("Engineer"), closeSoftKeyboard() );

回答6:

If you're using Genymotion, you may need to switch the default keyboard in Genymotion Configuration (it's an app on the emulator).

1. Go to Apps -> Genymotion Configuration -> Keyboard -> Virtual keyboard (click "Yes" when you're prompted to reboot)

NOTE: These changes do not persist after you close the emulator. You will need to set this every time you start the emulator.

I fixed this issue by setting layout_height="wrap_content" on the View I wanted to click(). Maybe it can help someone here.
