I am trying to print a .txt file that my application saves via FileWriter.
The file it saves is /sdcard/StudentLatePass.txt
When the print button is clicked, the SD file is saved and then it needs to print. I've been following the google cloud print tutorial.
package com.android.upgrayeddapps.latepass;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.Button;
import android.widget.Toast;
public class StudentActivity extends Activity
{
EditText txtData;
Button btnPrintTardy;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.student);
//Displays the Custom dialog for student login
AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext = this;
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE) ;
View layout = inflater.inflate(R.layout.studentlogin, null);
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
alertDialog.show();
txtData = (EditText) findViewById(R.id.editText1);
btnPrintTardy = (Button) findViewById(R.id.btnPrintTardy);
btnPrintTardy.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// write on SD card file data in the text box
try {
File myFile = new File("/sdcard/StudentLatePass.txt");
myFile.createNewFile();
FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter =
new OutputStreamWriter(fOut);
myOutWriter.append(txtData.getText());
myOutWriter.close();
fOut.close();
Toast.makeText(getBaseContext(),
"Done writing SD 'StudentLatePass.txt'",
Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(),
Toast.LENGTH_SHORT).show();
}
}// onClick
}); // btnWriteSDFile
btnPrintTardy.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//Print using Google Cloud Print
Intent printIntent = new Intent(this, PrintDialogActivity.class);
printIntent.setDataAndType(docUri, "text/plain");
printIntent.putExtra("title", "Student Late Pass");
startActivity(printIntent);
}// onClick
});// btnPrintSDFile
}
// Clear all activities on the top of the stack and deliver the intent to (on top now) MainActivity with a new Intent
public void onGotoLatePassActiviy(View View)
{
Intent intent = new Intent(View.getContext(), LatePassActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
StudentActivity.this.finish();
}
}
For the life of me I have tried to change the docUri, docMimeType and docTitle to everything under the sun to print this file.
My current modified code is
btnPrintTardy.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//Print using Google Cloud Print
Intent printIntent = new Intent(this, PrintDialogActivity.class);
printIntent.setDataAndType(docUri, "text/plain");
printIntent.putExtra("title", "Student Late Pass");
startActivity(printIntent);
}// onClick
});// btnPrintSDFile
I am still getting red squigglies under the docUri, and when i pass the intent to Print
