Question

我有一个带有2个按钮的简单应用程序，它会触发通知。后来在编程的进程中我想将正常的buttoms更改为图像buttoms因为更好的设计，所以我删除了正常的buttoms但是图像buttoms in和将id改回原来的 buttom1和buttom2，但现在它不再工作了。我做错了什么？我是否必须将图像按钮与正常图像不同？我必须安装libarys或somthing吗？请帮帮我！

的xml：

<ImageButton
    android:id="@+id/buttom2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/buttom1"
    android:layout_below="@+id/buttom1"
    android:layout_marginTop="23dp"
    android:src="@drawable/icon2" />

<ImageButton
    android:id="@+id/buttom1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginTop="14dp"
    android:src="@drawable/icon1" />

main.java：

public class MainActivity extends ActionBarActivity {

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


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;

    }


    public void sendNotification(View view) {

        switch(view.getId()){

            case R.id.buttom1:
                Notification1();
                break;

            case R.id.buttom2:
                Notification2();
                break;


            }
         }

   private void Notification1() {

       NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
       builder.setAutoCancel(true);
       builder.setContentTitle("BasicNotification");
       builder.setContentText("Test");
       builder.setSmallIcon(R.drawable.icon1);

       Notification notification = builder.build();
       NotificationManager manager = (NotificationManager) this.getSystemService(NOTIFICATION_SERVICE);
       manager.notify((int) System.currentTimeMillis(), notification);

    }

 private void Notification2() {

       NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
       builder.setAutoCancel(true);
       builder.setContentTitle("BasicNotification");
       builder.setContentText("Test");
       builder.setSmallIcon(R.drawable.icon2);

       Notification notification = builder.build();
       NotificationManager manager = (NotificationManager) this.getSystemService(NOTIFICATION_SERVICE);
       manager.notify((int) System.currentTimeMillis(), notification);

    }

}

预先感谢！

Answer 1

将此行添加到ImageButtons

 android:onClick="sendNotification"

Answer 2

你有没有改变

Button yourButton = (ImageButton) findViewById(R.id.btn);

到

ImageButton yourButton = (ImageButton) findViewById(R.id.btn);

此外，如果您向我们展示一些代码，我们将能够在您的查询中为您提供更多帮助。

动作不再适用于图像按钮？
