How To Fill An Activity With Text Stored In /raw

I have an app for a project. my idea was to create a 3 tab app, in each tab there are several buttons representing a topic. each topic has a txt file containing some information I

Solution 1:

You can open an asset txt file and read line by line like this:

InputStreaminput= context.getAssets().open(fileName);
DataInputStreamin=newDataInputStream(input);
BufferedReaderbr=newBufferedReader(newInputStreamReader(in));
String strLine;
//Read File Line By Linewhile ((strLine = br.readLine()) != null)   {
    // Print the content on the console
    System.out.println (strLine);
}
//Close the input stream
in.close();
} catch (Exception e){//Catch exception if any
    System.err.println("Error: " + e.getMessage());
}

This is a good start for you, display the lines you read in a TextView. Once you do this, you can move on to next step.

EDIT

package com.example.helloandroid;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

publicclassHelloAndroidextendsActivity {
   /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);

       // This is how you get the contextContextm_Context= getApplicationContext();

       // This is how you show text programatically, there is also xml option, which I recommend instead.TextViewtv=newTextView(this);
       tv.setText("Hello, Android");
       setContentView(tv);
}

publicclassContentHolderextendsActivity {

    String fileName;

    publicvoidonCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    Contextm_Context= getApplicationContext();

    TextViewtextview=newTextView(this);
    textview.setText("This is the content view");

    InputStream input;
    try {
        input = m_Context.getAssets().open(fileName);

    DataInputStreamin=newDataInputStream(input);
    BufferedReaderbr=newBufferedReader(newInputStreamReader(in));
    String strLine;
    // Read File Line By Linewhile ((strLine = br.readLine()) != null) {
        // Print the content on the console
        System.out.println(strLine);
        textview.setText(strLine);
    }
    // Close the input stream
    in.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    }

    setContentView(R.layout.main);
}
