Cara Menampilkan File Text ke TextView Android Ecipse

Selamat datang pengunjung muslihpedia kali ini saya akan share tentang cara menampilkan file txt ke TextView Android. langkah-langkahnya langsung saja:

• masuk ke folder res dan buat folder baru dengan nama raw
• kemudian masukan file txt anda di folder raw tersebut
• berikut desain layoutnya:

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <TextView

        android:id="@+id/hellotxt"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:text="Coba"

        tools:context=".MainActivity" />

</RelativeLayout>

• sintak ActivityMain.Java

package com.example.txtread;

import android.os.Bundle;

import android.text.Html;

import android.app.Activity;

import android.graphics.BitmapFactory;

import android.graphics.Shader.TileMode;

import android.graphics.drawable.BitmapDrawable;

import android.view.Menu;

import android.app.ActionBar;

import java.io.BufferedReader;

import java.io.ByteArrayOutputStream;

import java.io.FileReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.util.ArrayList;

import java.util.List;

import java.util.StringTokenizer;

import java.util.Vector;

import android.widget.TextView;

public class MainActivity extends Activity {

    String labels="caption";

    String text="";

    String[] s;

    private Vector<String> wordss;

    int j=0;

    private StringTokenizer tokenizer;

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        final ActionBar actionBar = getActionBar();

        BitmapDrawable background = new BitmapDrawable(BitmapFactory.decodeResource(getResources(), R.drawable.io1));

        backgroundsetTileModeX(android.graphics.Shader.TileMode.REPEAT);

        actionBar.setBackgroundDrawable(background);

        

        wordss = new Vector<String>();

        TextView helloTxt = (TextView)findViewById(R.id.hellotxt);

        helloTxt.setText(Html.fromHtml(readTxt()));

 }

    private void backgroundsetTileModeX(TileMode repeat) {

// TODO Auto-generated method stub

}

private String readTxt(){

     InputStream inputStream = getResources().openRawResource(R.raw.textsaya);

//     InputStream inputStream = getResources().openRawResource(R.raw.internals);

     System.out.println(inputStream);

     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

     int i;

  try {

   i = inputStream.read();

   while (i != -1)

      {

       byteArrayOutputStream.write(i);

       i = inputStream.read();

      }

      inputStream.close();

  } catch (IOException e) {

   // TODO Auto-generated catch block

   e.printStackTrace();

  }

     return byteArrayOutputStream.toString();

    }

}

kemudian jalankan dan lihat hasilnya.
