java - 在 Android Studio 中导入库 DirectoryChooser

问题描述

大家好，我是法国人，但我用英文写，谢谢你的放纵

我用 android studio 开发了我的第一个 android 应用程序

对于我的应用程序，我想建议在手机上选择一个文件夹

没有找到本机解决方案我尝试使用这个库： https ://github.com/passy/Android-DirectoryChooser

我没有成功导入它来帮助我使用 readme.MD

我发现很多话题都在谈论它

喜欢它：[如何导入 Android-DirectoryChooser][1] 但没有解决

我尝试使用 Maven Central 添加它，但没有成功

我尝试导入模块，但收到此错误：

Could not get unknown property 'GROUP' for object of type org.gradle.api.publication.maven.internal.deployer.DefaultGroovyMavenDeploy

谢谢你的帮助

简单的代码：

package com.example.newtest;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

import net.rdrei.android.dirchooser.DirectoryChooserActivity;
import net.rdrei.android.dirchooser.DirectoryChooserConfig;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                final Intent chooserIntent = new Intent(getApplication(), DirectoryChooserActivity.class);

                final DirectoryChooserConfig config = DirectoryChooserConfig.builder()
                        .newDirectoryName("DirChooserSample")
                        .allowReadOnlyDirectory(true)
                        .allowNewDirectoryNameModification(true)
                        .build();

                chooserIntent.putExtra(DirectoryChooserActivity.EXTRA_CONFIG, config);
// REQUEST_DIRECTORY is a constant integer to identify the request, e.g. 0
                startActivityForResult(chooserIntent, 2000);

            }
        });

    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 2000) {
            if (resultCode == DirectoryChooserActivity.RESULT_CODE_DIR_SELECTED) {
                Log.d("Directory", data.getStringExtra(DirectoryChooserActivity.RESULT_SELECTED_DIR));
            } else {
                // Nothing selected
            }
        }
    }
}

解决方案

好的，根据您提供的信息，试试这个

  • 将此库添加到您的依赖项 gradle
dependencies {
implementation  'net.rdrei.android.dirchooser:library:3.2@aar' // try this instead
}
  • 在应用程序标记内的清单文件中添加此行
<application>
    <activity android:name="net.rdrei.android.dirchooser.DirectoryChooserActivity" />
</application>
  • 添加这些 java 行
android {

    compileSdkVersion 28

    buildToolsVersion "30.0.0"



    defaultConfig {

        applicationId "com.example.transfertlocal2"

        minSdkVersion 22

        targetSdkVersion 28

        versionCode 1

        versionName "1.0"



        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

    }

   ////add these lines 
   compileOptions
            {
                sourceCompatibility JavaVersion.VERSION_1_8
                targetCompatibility JavaVersion.VERSION_1_8
            }


    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

        }

    }

}
