Question

Ich habe einen editText und ich habe eine Schaltfläche, die die Farbe, Größe und Schrift ändert, also beim Speichern der Datei als pdf oder txt Datei wie bekomme ich die 3 Dinge mit dem Text Ich bekomme nur den Text mit normalem Schwarz Stil das ist mein Code.

size.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      txtSpeechInput.setTextSize(25); 
      txtSpeechInput.setTextColor(Color.rgb(150,0,0)); 
      txtSpeechInput.setTypeface(null, Typeface.BOLD); 

der Code speichern:

final File externalStorageDir = new File(
        Environment 
          .getExternalStorageDirectory(), "MyVoiceText"); 

      boolean success = true; 
      if (!externalStorageDir.exists()) { 
       success = externalStorageDir.mkdirs(); 
      } 

      if (success) { 
       final Dialog dialog2 = new Dialog(MainActivity.this); 
       dialog2.setContentView(R.layout.dialog_save); 
       dialog2.show(); 
       editsave = (EditText) dialog2.findViewById(R.id.edit_save); 
       pdf = (Button) dialog2.findViewById(R.id.pdf_save); 
       pdf.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         pdf.setEnabled(false); 
         txt.setEnabled(true); 

        } 
       }); 

       txt = (Button) dialog2.findViewById(R.id.txt_save); 
       txt.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         txt.setEnabled(false); 
         pdf.setEnabled(true); 

        } 
       }); 
       dia_save = (Button) dialog2.findViewById(R.id.dia_save); 
       dia_save.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         String savename = editsave.getText().toString(); 

         if(!txt.isEnabled()) { 
          File myFile = new File(externalStorageDir + "/" + savename + ".txt"); 

           File myFile = new File(externalStorageDir + "/" + savename + ".txt"); 

          try { 
           StringBuffer string = new StringBuffer(); 

           string.append(txtSpeechInput.getText().toString()); 
           Properties properties = new Properties(); 
           // set the properties value 
           properties.put("text",string.append(txtSpeechInput.getText().toString()));         properties.put("textstyle","bold"); 
           properties.put("typeface",txtstyle); 
           properties.put("etxtColor",txtcolor); 

           FileOutputStream fOut = new FileOutputStream(myFile); 
           OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut); 
           myOutWriter.append(string); 

           myOutWriter.close(); 
           fOut.flush(); 
           fOut.close(); 
          } catch (Exception e) { 

          } 


          try { 
           myFile.createNewFile(); 
          } catch (IOException e) { 
           e.printStackTrace(); 
          } 
          dialog2.dismiss(); 
         }else if(!pdf.isEnabled()){ 
          try 
          { 

           String savename2 = editsave.getText().toString(); 

           String takeit = txtSpeechInput.getText().toString(); 

            Document document = new Document(PageSize.A4); 
           Paragraph p = new Paragraph(); 
           PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(Environment.getExternalStorageDirectory() + "/MyVoiceText/" +savename2+".pdf")); 
           document.open(); 
           writer.getDirectContent(); 
           p.add(new Phrase(takeit)); 



           document.add(p); 

           document.close(); 
           Log.d("OK", "done"); 

         } catch (Exception e) { 
          //LOGGER.error(e.getMessage()); 
         } 

laden Sie die Textdatei

File sdcard = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/MyVoiceText/"); 
         //Get the text file 
        File file = new File(sdcard, String.valueOf(selected)); 
         InputStream input = null; 
         try { 
          input = new FileInputStream(file); 
          Properties prop = new Properties(); 
          // load a properties file 
          prop.load(input); 
         }catch (Exception e){ 
          e.printStackTrace(); 
         } 
         //Read text from file 
         StringBuilder text = new StringBuilder(); 

         try { 
          BufferedReader br = new BufferedReader(new FileReader(file)); 
          String line; 

          while ((line = br.readLine()) != null) { 
           text.append(line); 

          } 
          br.close(); 
         catch (IOException e) { 
          //You'll need to add proper error handling here 
         } 

Answer 1

von Code, so scheint es, wie Sie iTextPDF Bibliothek werden mit dem PDF zu erzeugen. Einsatz Font-Klasse von iTextPDF eine neue Schriftart erstellen und wie unten verwenden:

private static Font HelveticaBlue = new Font(Font.FontFamily.HELVETICA, 6, 
      Font.BOLD, BaseColor.BLUE); 
new Paragraph("Blue ColorText"), HelveticaBlue); 

Answer 2

Wir Properties hinzufügen können, dass enthält Einträge in Schlüssel-Wert-Format in Datei.

Und wir können unsere eigenen Properties in File auch abrufen.

wie unten Code:

schreiben auf Dateieigenschaften:

private void addPropertiesToFile(String mytext){ 
     try { 
      String root = Environment.getExternalStorageDirectory().toString(); 
      File myDir = new File(root + "/CHETAN"); 
      if (!myDir.exists()) 
      myDir.mkdirs(); 
      String fname = "mytext.txt"; 
      File myFile = new File (myDir, fname); 
      if (!myFile.exists()) 
      myFile.createNewFile(); 
      Properties properties = new Properties(); 
      // set the properties value 
      properties.put("text","dsf"); 
      properties.put("textstyle","bold"); 
      properties.put("typeface","arial"); 
      properties.put("etxtColor","green"); 

      FileOutputStream fOut = new FileOutputStream(myFile); 
      OutputStreamWriter myOutWriter =new OutputStreamWriter(fOut); 
      myOutWriter.write(mytext); 
      // save properties to project root folder 
      properties.store(myOutWriter,null); 
      myOutWriter.close(); 
      fOut.flush(); 
      fOut.close(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

Eigenschaften Abrufen von Datei:

private void retrievePropertiesFromFile(){ 
     String root = Environment.getExternalStorageDirectory().toString(); 
     File myDir = new File(root + "/CHETAN"); 
     String fname = "mytext.txt"; 
     File myFile = new File (myDir, fname); 

     InputStream input = null; 
     try { 
     input = new FileInputStream(myFile); 
     Properties prop = new Properties(); 
     // load a properties file 
     prop.load(input); 
     // get the property value and print it out 
     Log.i(getClass().getSimpleName(),prop.getProperty("text")); 
     Log.i(getClass().getSimpleName(),prop.getProperty("textstyle")); 
     Log.i(getClass().getSimpleName(),prop.getProperty("typeface")); 
     Log.i(getClass().getSimpleName(),prop.getProperty("typeface")); 
     } catch (Exception ex) { 
      ex.printStackTrace(); 
     } finally { 
      if (input != null) { 
       try { 
        input.close(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 
      } 
     } 

    }
