　　2.读取文件的主要代码

　　读取主代码

　　1 Button bRead=(Button)findViewById(R.id.read); 2 bRead.setOnClickListener(new View.OnClickListener() { 3 4 @Override 5 public void onClick(View v) { 6 // TODO Auto-generated method stub 7 //此时隐藏了文件内容框和文件内容的label 8 filecontent.setVisibility(View.GONE); 9 TextView content=(TextView)findViewById(R.id.content);10 content.setVisibility(View.GONE);11 InputStream inStream;12 file_name=filename.getText().toString();13 14 /* API15 * FileInputStream openFileInput (String name) 16 * Open a private file associated with this Context's application package for reading. 17 */18 try {19 inStream = FileStoreActivity.this.openFileInput(file_name);20 String context=FileService.read(inStream).toString();21 Toast.makeText(FileStoreActivity.this, context, Toast.LENGTH_LONG).show();22 } catch (Exception e) {23 Log.e(TAG,e.toString());24 resId=R.string.error;25 }26 }27 });

　　3.关于编者的代码

　　关于编码代码

　　Button bAbout=(Button)findViewById(R.id.about); bAbout.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub new AlertDialog.Builder(FileStoreActivity.this).setTitle("编者信息") .setMessage( "编者： naive_monk" + " " + "爱好：篮球、音乐、交友" + " " + "Q　Q：1271522052" + " " + "邮箱：summerdir@gmail.com" + " " + "所在城市：广东惠州 " + " ") .setCancelable(false).setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(
