android - Android 显示与图像文件同名的文本文件

Question

现在我有一个非常简单的应用程序，我可以在其中拍照，然后回答问题。我将图片的文件名捆绑到问题类中，然后使用相同的文件名将问题保存为文本文件（这些都保存在 SD 卡上）。现在我要做的是在选择该图片时显示该文本文件（它将显示在 TextView 中）。所以我的问题是有没有办法显示一个文本文件，它与一个选定的图像文件同名TextView？我还没有找到其他类似的东西，尽管这似乎不是一个不常见的任务。

我的代码如下：

创建图像文件名：

ImageButton button;
static int data = 0;

button.setOnClickListener(new View.OnClickListener() {              
    public void onClick(View v) { 
        i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        String root = Environment.getExternalStorageDirectory().toString();
        File myDir = new File(root + "/MyDirectory/");    
        myDir.mkdirs();

        if (myDir.exists()) { }

        Random generator = new Random(); 
        int n = 10000;
        n = generator.nextInt(n);
        String fname = "Image-"+ n +".jpg";
        text.setText(fname);

        File file = new File (myDir, fname);
        Uri uriSavedImage = Uri.fromFile(file);  
        Bundle basket = new Bundle();
        basket.putString("key", fname);

        sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+ Environment.getExternalStorageDirectory())));
        Intent is = new Intent(Home.this, Details.class);
        is.putExtras(basket);
        i.putExtra("output", uriSavedImage);
        startActivity(is);
        startActivityForResult(i, data); 
    }
});

创建文本文件名：

textfileName = (TextView)findViewById(R.id.textFile);
Button save;
TextView question;

Bundle gotBasket = getIntent().getExtras();
gotBread = gotBasket.getString("key");
textfileName.setText(gotBread);

save.setOnClickListener(new View.OnClickListener() {
    public void onClick(View arg0) {
        Toast.makeText(getApplicationContext(), "Details Saved!", Toast.LENGTH_SHORT).show();
        textQuestion= question.getText().toString();

        String root = Environment.getExternalStorageDirectory().toString();
        File myDir = new File(root + "/MyDirectory/");    
        myDir.mkdirs();

        if (myDir.exists()) { }

        detailsFile = textfileName.getText().toString() + ".txt";
        File file = new File (myDir, detailsFile);

        try {
            BufferedWriter writer = new BufferedWriter(new FileWriter(file,true));
            writer.write(textQuestion);
            writer.newLine();
            writer.flush();
            writer.close();
        } catch (IOException e) { e.printStackTrace(); }
    }
});

显示已选择图像的文件：

final Button viewBtn = (Button)findViewById(R.id.detailsBtn);

viewBtn.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        final int len = thumbnailsselection.length;
        int cnt = 0;
        String selectImages = "";

        for (int i = 0; i<len; i++) {
            if (thumbnailsselection[i]) {
                cnt++;
                selectImages = selectImages + arrPath[i] + "|";
            }
        }

        if (cnt == 0) {
            Toast.makeText(getApplicationContext(), "Please Select One Picture", Toast.LENGTH_SHORT).show();
        } else if  (cnt > 1) {
            Toast.makeText(getApplicationContext(), "Please Select Only One Picture", Toast.LENGTH_SHORT).show();
        } else if (cnt == 1) {




setContentView(R.layout.details_text);
                        detailsView = (TextView)findViewById(R.id.displayDetails); 
                        File dir = Environment.getExternalStorageDirectory();
                        File myFile = new File(dir, "/MyDirectory/" + "detailsFile-.txt");

                        if (myFile.exists()) {
                            StringBuilder text = new StringBuilder();
                            try {
                                BufferedReader br = new BufferedReader(new FileReader(myFile));
                                String line;

                                while ((line = br.readLine()) != null) {
                                    text.append(line);
                                }
                            }
                            catch (IOException e) {

                            }   
                            detailsView.setText(text);
                        }
                        else
                        {
                            Toast.makeText(getApplicationContext(), "File Doesn't Exist", Toast.LENGTH_SHORT).show();
                        }
                        }

                    }

            });

我else if试图在TextView.
