Question

我从gmail下载了一个文件。下载完成后，我需要能够点击通知，在我的应用程序中打开下载的文件。我的文件类型是csv。

点击上面通过我的app.how打开的下载文件打开？

<activity
            android:label="@string/app_name"
            android:name=".Fakeactivity">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="file" />
                <data android:host="*" />
                <data android:mimeType="text/comma-separated-values" />
                <data android:pathPattern=".*\\.csv" />
            </intent-filter> 
        </activity>

使用上面的代码通过我的app.in FakeActivty打开csv文件我已经编写了读取csv文件的代码。

have you implement function of click on notification and your program can handle open csv files here is a code for read csv file here is the code of opening activity which will response for show the csv file

   final Intent intent = new Intent(this, CSVClass.class);
      \\ data you want to send to CSV
    intent.putExtra("key", "value");
    final PendingIntent contentIntent = 
     PendingIntent.getActivity(this,  
      0, intent), 0);
  public class CSVFile {
  InputStream inputStream;

  public CSVFile(InputStream inputStream){
    this.inputStream = inputStream;
  }

   public List read(){
    List resultList = new ArrayList();
    BufferedReader reader = new BufferedReader(new 
    InputStreamReader(inputStream));
    try {
        String csvLine;
        while ((csvLine = reader.readLine()) != null) {
            String[] row = csvLine.split(",");
            resultList.add(row);
        }
    }
    catch (IOException ex) {
        throw new RuntimeException("Error in reading CSV file: "+ex);
    }
    finally {
        try {
            inputStream.close();
        }
        catch (IOException e) {
            throw new RuntimeException("Error while closing input   
        stream: "+e);
        }
    }

    }
