ボタンを押すとPDFファイルを作成しようとしています。私はiTextライブラリを使用しています。
私の活動:
package com.pdf;
import java.io.FileOutputStream;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import com.itextpdf.text.Document;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
public class PDFActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void GenerarPDF(View view)throws Exception{
Document document=new Document();
PdfWriter.getInstance(document,new FileOutputStream("generando.pdf"));
document.open();
document.add(new Paragraph("Testing testing and testing"));
document.close();
}
}
私のxml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
