我试图通过调用getAbsolutePath()来显示文件的路径,但是应用程序
什么都不显示。
Java代码:
public void createExternalStorageDirectory() {
File file = new File(getExternalFilesDir(null), fileName);
try {
InputStream is = getResources().openRawResource(R.drawable.ic_launcher);
OutputStream os = new FileOutputStream(file);
byte[] data = new byte[is.available()];
is.read(data);
os.write(data);
Toast.makeText(getBaseContext(), file.getAbsolutePath(), Toast.LENGTH_SHORT).show();
is.close();
os.close();
} catch (IOException e) {
Log.w("ExternalStorage", " Error writing " + file, e);
}
}

您可以尝试使用Environment.getExternalStorageDirectory()而不是getExternalFilesDir(null)

将外部文件权限添加到清单文件:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
尝试使用getBaseContext()
的getApplicationContext()intead
