根據編號顯示錯誤消息。嘗試？

Question

我是新來的java和Android。在下面的代碼片段中，當用戶名爲&的密碼不正確時，我顯示一條錯誤消息。現在，我需要在2次錯誤嘗試後在錯誤消息中添加一些額外的信息。 如果我需要設置一個計數器來識別嘗試？ 我該怎麼做？

public void testBadCredentials() throws Exception { 
    RestClientFactoryTest.setPrefixAllInstances("login-failure"); 
    XMLRPCFactoryTest.setPrefixAllInstances("login-failure"); 
    mSolo.enterText(0, "test"); //username 
    mSolo.enterText(1, "test"); //password 
    mSolo.clickOnText(mSolo.getString(R.string.sign_in)); 
    boolean errorMessageFound = mSolo.searchText(mSolo.getString(R.string.username_or_password_incorrect)); 
    assertTrue("Error message not found", errorMessageFound); 
}

private static n0_attamp = 0; 
public void testBadCredentials() throws Exception { 
n0_attamp++; 
RestClientFactoryTest.setPrefixAllInstances("login-failure"); 
XMLRPCFactoryTest.setPrefixAllInstances("login-failure"); 
mSolo.enterText(0, "test"); //username 
mSolo.enterText(1, "test"); //password 
mSolo.clickOnText(mSolo.getString(R.string.sign_in)); 
boolean errorMessageFound = mSolo.searchText(mSolo.getString(R.string.username_or_password_incorrect)); 
if(n0_attamp = 3) 
{ 
    assertTrue("3rd try", errorMessageFound); 
    //reinitialize counter 
    n0_attamp = 0; 
} 
else 
assertTrue("Error message not found", errorMessageFound); 
}
