The below code this will help you

public class TextProperty {
    private int heigt;                              //读入文本的行数
    private String []context = new String[1024];    //存储读入的文本

    /*
     *@parameter wordNum
     *
     */
    public TextProperty(int wordNum ,InputStreamReader in) throws Exception {
        int i=0;
        BufferedReader br = new BufferedReader(in);
        String s;
        while((s=br.readLine())!=null){
            if(s.length()>wordNum){
                int k=0;
                while(k+wordNum<=s.length()){
                    context[i++] = s.substring(k, k+wordNum);
                    k=k+wordNum;
                }
                context[i++] = s.substring(k,s.length());
            }
            else{
                context[i++]=s;
            }
        }
        this.heigt = i;
        in.close();
        br.close();
    }


    public int getHeigt() {
        return heigt;
    }

    public String[] getContext() {

        return context;
    }
}

public class MainActivity extends AppCompatActivity {

    private Button btn;
    private ImageView iv;
    private final int WORDNUM = 35;  //转化成图片时  每行显示的字数
    private final int WIDTH = 450;   //设置图片的宽度

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        iv = (ImageView) findViewById(R.id.imageView);
        btn = (Button) findViewById(R.id.button);

        btn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                int x=5,y=10;
                try {
                    TextProperty tp = new TextProperty(WORDNUM, new InputStreamReader(getResources().getAssets().open("1.txt")));
                    Bitmap bitmap = Bitmap.createBitmap(WIDTH, 20*tp.getHeigt(), Bitmap.Config.ARGB_8888);
                    Canvas canvas = new Canvas(bitmap);
                    Paint paint = new Paint();
                    paint.setColor(Color.WHITE);
                    paint.setTextAlign(Paint.Align.LEFT);
                    paint.setTextSize(20f);

                    String [] ss = tp.getContext();
                    for(int i=0;i
