在谷歌驱动器上保存文件

如何解决在谷歌驱动器上保存文件

嘿，我正在尝试执行应用程序，在其中检查我的当前位置并将此位置保存在“.txt”文件中。我的应用程序在每个“用户设置时间”秒内保存此位置。这是工作。另外我想将保存文件添加到谷歌驱动器。但我不知道怎么做。有什么方法可以创建文件夹并保存“.txt”文件，就像我在本地文件夹中所做的一样？

public class Save extends AppCompatActivity {
    boolean sms = false;
    int n_seconds,n_minutes,n_sum;
    private String path = Environment.getExternalStorageDirectory().toString() + "/Loc/Save";
    private Button buttonStartThread;
    private Handler mainHandler = new Handler();
    private volatile boolean stopThread = false;
    NumberPicker edit_text_input_back,edit_text_input_back_2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_background);
        buttonStartThread = findViewById(R.id.button_start_thread);

        edit_phone_number = findViewById(R.id.edit_phone_number);
        edit_mail = findViewById(R.id.edit_email);
        edit_text_input_back = (NumberPicker) findViewById(R.id.edit_text_input_back);
        edit_text_input_back.setMaxValue(60);
        edit_text_input_back.setMinValue(0);
        edit_text_input_back.setValue(0);
        edit_text_input_back_2 = (NumberPicker) findViewById(R.id.edit_text_input_back_2);
        edit_text_input_back_2.setMaxValue(60);
        edit_text_input_back_2.setMinValue(0);
        edit_text_input_back_2.setValue(0);
        edit_text_input_back.setonValueChangedListener(new NumberPicker.OnValuechangelistener() {
            @Override
            public void onValueChange(NumberPicker numberPicker,int i,int i1) {
            n_seconds = i1;
            }
        });
        edit_text_input_back_2.setonValueChangedListener(new NumberPicker.OnValuechangelistener() {
            @Override
            public void onValueChange(NumberPicker numberPicker,int i1) {
                n_minutes = 60 * i1;

解决方法

您可以检查大量来源以创建文件夹并将文件上传到 Google 云端硬盘

Creating Folder

File fileMetadata = new File();
fileMetadata.setName("Invoices");
fileMetadata.setMimeType("application/vnd.google-apps.folder");

File file = driveService.files().create(fileMetadata)
    .setFields("id")
    .execute();
System.out.println("Folder ID: " + file.getId());

Uploading File

File fileMetadata = new File();
fileMetadata.setName("photo.jpg");
java.io.File filePath = new java.io.File("files/photo.jpg");
FileContent mediaContent = new FileContent("image/jpeg",filePath);
File file = driveService.files().create(fileMetadata,mediaContent)
    .setFields("id")
    .execute();
System.out.println("File ID: " + file.getId());

对于 txt 文件的特定 mime 类型，您可能需要参考此 StackOverflow post (text/plain)。有关特定 Google 应用程序 MIME 类型，请参阅 documentation。
