Posted 2021-06-21 zhangjin1120

• 添加jitpack库：

allprojects {
    repositories {
       ...
        maven { url 'https://jitpack.io' }
    }
}

• 添加依赖，0.10.2版本使用的是rxjava2

    implementation 'com.github.tbruyelle:rxpermissions:0.10.2'
    implementation 'io.reactivex.rxjava2:rxjava:2.2.8'

• androidManifest.xml中申请权限：

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

• MainActivity.java中的使用：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new RxPermissions(MainActivity.this)
                .request(Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE)
                .subscribe(new Consumer<Boolean>() {
                    @Override
                    public void accept(Boolean aBoolean) throws Exception {
                        if (aBoolean) {

                        } else {

                        }
                    }
                });
    }
}
