登录成功后，意图未打开

Question

我有问题，我的意图在成功登录后无法打开。它表明我的应用程序已停止工作。我无法弄清楚为什么？

// check if the Stored password matches with  Password entered by user
if(password.equals(storedPassword))
{
    Toast.makeText(HomeActivity.this, "Congrats: Login Successfull", Toast.LENGTH_LONG).show();
    dialog.dismiss();
    **Intent i = new Intent (getApplicationContext(), FirstInterface.class);
    startActivity(i); // HERE IS THE INTENT CODING
} else {
    Toast.makeText(HomeActivity.this,
                   "User Name or Password does not match", 
                   Toast.LENGTH_LONG).show();
}

我应该在FirstInterface.class中插入什么内容？

公共类FirstInterface扩展了Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

Answer 1

确保清单中出现FirstInterface，如下所示：

<activity
    android:name=".FirstInterface"
    android:label="@string/app_name" >
</activity>

并使用您的活动上下文启动新活动，如下所示：

Intent i = new Intent (HomeActivity.this, FirstInterface.class);
startActivity(i);
