所以我嘗試推出我的第二個活動是「dummy.class」一旦點擊通知,新的活動不會啓動
爲其代碼是在這裏:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
public class dummy extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dummy);
}
}
我想要做到這一點,當我點擊由這個代碼在我的MainActivity生成通知:
public class MainActivity extends AppCompatActivity
{
int notifyId = 1;
int messages = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b1 = (Button) findViewById(R.id.gen_notif);
}
public void createNotif(View v)
{
messages += 1;
notifyId += 1 ;
NotificationManager notificationManager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent intent=new Intent(MainActivity.this ,dummy.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,(int) System.currentTimeMillis(),intent,0);
NotificationCompat.Builder n = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setContentTitle("Hello")
.setContentText("Hello World Notification")
.setContentIntent(pendingIntent)
.setSmallIcon(R.mipmap.ic_launcher)
.setNumber(messages)
.setAutoCancel(true);
notificationManager.notify(notifyId,n.build());
}
這裏是activity_main的XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.manan.notif.MainActivity">
<Button
android:id="@+id/gen_notif"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/b_text"
android:onClick="createNotif"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
但是,當我點擊通知時,它什麼都不做(除了由於代碼導致本身無效)。我只是在學習,所以我不知道自己做錯了什麼,可以使用另一雙眼睛。
