    <p>I made a simple application that will log a user input from an editText and it will put it into a csv on my sdcard. Now my problem is reading that csv and making it as a variable for the next activity on my app.</p> <p>Here is my main activity:</p> <pre><code>package com.willardcuizon.differentialgps; import java.io.File; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.app.Activity; import android.content.Context; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; public class Main extends Activity implements OnClickListener{ Button start; EditText lat; EditText lon; LocationListener loclist; CSVFileWriter csv; StringBuffer filePath; File file; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); start = (Button) findViewById(R.id.button1); start.setOnClickListener(this); lat = (EditText) findViewById(R.id.editText1); lon = (EditText) findViewById(R.id.editText2); filePath = new StringBuffer(); filePath.append("/sdcard/surveyedGPS.csv"); file = new File(filePath.toString()); csv = new CSVFileWriter(file); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public void onClick(View v) { // TODO Auto-generated method stub if(v.getId()==R.id.button1){ LocationManager locman = (LocationManager)getSystemService(Context.LOCATION_SERVICE); if(locman.isProviderEnabled(LocationManager.GPS_PROVIDER)){ Toast.makeText( getApplicationContext(), "GPS is Enabled.", Toast.LENGTH_SHORT ).show(); csv.writeHeader(lat.getText().toString()); csv.writeHeader(lon.getText().toString()); } else{ Toast.makeText( getApplicationContext(), "GPS is Disabled.Please enable GPS", Toast.LENGTH_SHORT ).show(); } } } } </code></pre> <p>And here is my CSVWriter Class:</p> <pre><code>package com.willardcuizon.differentialgps; import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.io.PrintWriter; public class CSVFileWriter { private PrintWriter csvWriter; private File file; public CSVFileWriter(File file) { this.file = file; } public void writeHeader(String data) { try { if (data != null) { csvWriter = new PrintWriter(new FileWriter(file, true)); csvWriter.print(","); csvWriter.print(data); csvWriter.close(); } } catch (IOException e) { e.printStackTrace(); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
