Android:无法使用Intents启动新活动

Question

我按下按钮时尝试启动一个新活动,但没有任何反应,我没有错误.这是我的代码:

主要活动

public class CSLearn_Python_AppActivity extends Activity {


String tag = "Events";

/** Called when the activity is first created. */


@Override
public void onCreate(Bundle savedInstanceState) {


    //get content from main.xml
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



    Button login = (Button) findViewById(R.id.loginBtn);
    login.setOnClickListener(new OnClickListener(){
        public void onClick(View v){



//              Intent intent = new Intent("com.Main.Verification");   
//              startActivity(intent);

            Intent myIntent = new Intent(getBaseContext(), Verification.class);
            startActivity(myIntent);

        }
    });



 }

新的活动

    import android.app.Activity;
import android.os.Bundle;

public class Verification extends Activity{

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.verification);

}

}

验证XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/linearLayout1" android:layout_width="match_parent" android:baselineAligned="true" android:layout_height="match_parent" android:layout_gravity="center" android:gravity="center" android:orientation="vertical">
    <TextView android:text="@string/Verification" android:id="@+id/Verrification" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
    <EditText android:layout_height="wrap_content" android:id="@+id/password" android:inputType="textPassword" android:layout_width="112dp">
        <requestFocus></requestFocus>
    </EditText>
    <Button android:text="@string/LoginBtn" android:id="@+id/loginBtn" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>

我把它添加到了android宣言中

<activity android:name=".Verification"
              android:label="Verification">
        <intent-filter>
            <action android:name="com.Main.VERIFICATION" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

如果有人能指出我正确的方向,那将非常感激.

尝试以下代码并在AndroidManifest.xml文件中注册您的活动:

Intent myIntent = new Intent(CSLearn_Python_AppActivity.this, Verification.class);
startActivity(myIntent);
