android - 如何在抽屉导航布局中添加图像标题

Question

我正在尝试在抽屉布局的 ListView 中应用图像标题。这就是我到目前为止所得到的。

但是在点击通知时，它会打开 School Fragment。点击 School 会打开 Whats 的热门 fragment 。问题是插入作为 ListView 一部分的图像标题时。我需要将它作为标题应用。这是我当前使用的代码:

Java:

View header=getLayoutInflater().inflate(R.layout.header, null);
 ImageView pro=(ImageView)header.findViewById(R.id.profile_image);
 pro.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View arg0) {
 // TODO Auto-generated method stub
 Toast.makeText(getApplicationContext(), "Clicked",                                                                       Toast.LENGTH_SHORT).show();
  }
  });
 mDrawerList.addHeaderView(header);

XML:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
    <RelativeLayout
        android:id="@+id/RelativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="80dp"
        android:background="@drawable/header" >
        <TextView
            android:id="@+id/textView1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentTop="true"
            android:layout_margin="5dp"
            android:layout_toRightOf="@+id/profile_image"
            android:gravity="center_vertical"
            android:text="Welcome to Snappy"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="#FFFFFF"
            android:textStyle="bold" />
        <ImageView
            android:id="@+id/profile_image"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_alignParentLeft="true"
            android:layout_centerVertical="true"
            android:background="@drawable/icon"
            android:layout_margin="5dp"
            android:gravity="center_vertical" />
    </RelativeLayout>
</FrameLayout>

我需要做的只是在单击某个项目时在我的位置添加 +1。这将增加一个由页眉占用的位置。像这样:

public void onItemClick(AdapterView parent, View view, int position, long id) { //显示所选抽屉导航项目的 View 显示 View (位置+1)；
