Java 从getExternalStorageDirectory到内部存储

我再次需要你的帮助。我有这个简单的照片应用程序的代码，但这个代码保存在SD卡编辑的图像，但我想改变这个保存在手机内存的图像

private File captureImage() {
    // TODO Auto-generated method stub
    OutputStream output;

    Calendar cal = Calendar.getInstance();

    Bitmap bitmap = Bitmap.createBitmap(ll1.getWidth(), ll1.getHeight(),
            Config.ARGB_8888);

    /*
     * bitmap = ThumbnailUtils.extractThumbnail(bitmap, ll1.getWidth(),
     * ll1.getHeight());
     */
    Canvas b = new Canvas(bitmap);
    ll1.draw(b);

    // Find the SD Card path
    File filepath = Environment.getExternalStorageDirectory();

    // Create a new folder in SD Card
    File dir = new File(filepath.getAbsolutePath() + "/background_eraser/");
    dir.mkdirs();

    mImagename = "image" + cal.getTimeInMillis() + ".png";

    // Create a name for the saved image
    file = new File(dir, mImagename);

    // Show a toast message on successful save
    Toast.makeText(SelectedImgActivity.this, "Image Saved to SD Card",
            Toast.LENGTH_SHORT).show();

    try {

        output = new FileOutputStream(file);
        // Compress into png format image from 0% - 100%
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
        output.flush();
        output.close();
    }

    catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return file;

}

有什么建议吗？我想我必须只将Environment.getExternalStorageDirectory更改为其他内容，但是什么呢

谢谢大家!

编辑：

我将这一行更改为

filepath=Environment.getDataDirectory（）；我认为这是可行的。但是这个在根文件夹中创建新文件夹…我希望它在图片中。。。如何对此进行存档？

编辑2：

现在我被编辑成这个代码

private File captureImage() {
    // TODO Auto-generated method stub
    OutputStream output;

    Calendar cal = Calendar.getInstance();

    Bitmap bitmap = Bitmap.createBitmap(ll1.getWidth(), ll1.getHeight(),
            Config.ARGB_8888);

    /*
     * bitmap = ThumbnailUtils.extractThumbnail(bitmap, ll1.getWidth(),
     * ll1.getHeight());
     */
    Canvas b = new Canvas(bitmap);
    ll1.draw(b);

    // Find the SD Card path
    File filepath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
//  File filepath = Environment.getDataDirectory(Environment.DIRECTORY_PICTURES);

    // Create a new folder in SD Card
    File dir = new File(filepath.getAbsolutePath() + "/Background Remover/");

    dir.mkdirs();

    mImagename = "image" + cal.getTimeInMillis() + ".png";

    // Create a name for the saved image
    file = new File(dir, mImagename);

    // Show a toast message on successful save
    Toast.makeText(SelectedImgActivity.this, "Image Saved",
            Toast.LENGTH_SHORT).show();

    try {

        output = new FileOutputStream(file);
        // Compress into png format image from 0% - 100%
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
        output.flush();
        output.close();
    }

    catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return file;

}

一切都很好，除了吐司秀

替换：

File dir = new File(filepath.getAbsolutePath() + "/background_eraser/");

与：

您可以使用：

FileInputStream fis = context.openFileInput(name);

在API级别1中添加

返回文件系统上存储使用openFileOutput（String，int）创建的文件的目录的绝对路径

FileInputStream fis = context.openFileInput(name);
