android - 为什么我使用 sendKeys() 的测试在 Android 模拟器中没有动画？

Question

当我在 Android 模拟器中运行以下测试时，输入值未显示在 EditText 中。为什么不呢？我需要更改什么才能在模拟器中看到输入？ (测试通过，所以最后，这可能并不重要。我只是希望能够在模拟器中看到它实际发生。)

public void testOkButtonOnClickWithUserInputNumber() throws Throwable {
    this.sendKeys(Integer.toString(this.testNumber)); // 123

    this.runTestOnUiThread(new Runnable() {
        @Override
        public void run() {
            Assert.assertTrue(NumberFilterTest.this.okButton.performClick());
        }
    });

    this.getInstrumentation().waitForIdle(new Runnable() {
        @Override
        public void run() {
            Assert.assertTrue(NumberFilterTest.this.activity.isFinishing());
        }
    });
}

查看官方开发指南 - Activity Testing .

1 确保触摸模式已关闭:

To control the emulator or a device with key events you send from your tests, you must turn off touch mode. If you do not do this, the key events are ignored.

 ActivityInstrumentationTestCase2.setActivityTouchMode(false);

2 确保屏幕已解锁:

You may find that UI tests don't work if the emulator's or device's home screen is disabled with the keyguard pattern. This is because the application under test can't receive key events sent by sendKeys().

 mKeyGuardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
 mLock = mKeyGuardManager.newKeyguardLock("activity_classname");
 mLock.disableKeyguard();
