How to Get ImageView Click Event in Android Appium TestCase

Simple Button Click Event Example.

        WebElement test=driver.findElement(By.name("Test"));
	String str = btnLogin.getText();
	Assert.assertTrue(str.contains("Test"));
	test.click();

Seems like you are referring to some other variable while assigning a value to str which is not shared by you in the post :

WebElement test=driver.findElement(By.name("Test"));
String str = btnLogin.getText();

btnLogin and test are different elements. OR you might wanted to use :

  WebElement test=driver.findElement(By.name("Test"));
	String str = test.getText();
