PermissionsDispatcher动态权限申请

Android对6.0及以上的版本做了更强的权限控制。如打电话这种需要动态申请。我推荐使用github上start最多的PermissionsDispatcher作为权限管理。

一,使用的Androidstudio版本为3.5.3

二,使用的permissionsdispatcher版本为3.2.0

github地址为：https://github.com/permissions-dispatcher/PermissionsDispatcher

 

基本步骤如下：

AndroidManifest
1.将以下行添加到AndroidManifest.xml：

2.仓库地址：

repositories {
  jcenter()
  maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
}

3.添加依赖

dependencies {
  implementation "org.permissionsdispatcher:permissionsdispatcher:${latest.version}"
  annotationProcessor "org.permissionsdispatcher:permissionsdispatcher-processor:${latest.version}"
}

4.添加代码：

package com.***.***.module.my.active;

import permissions.dispatcher.NeedsPermission;
import permissions.dispatcher.OnNeverAskAgain;
import permissions.dispatcher.OnPermissionDenied;
import permissions.dispatcher.RuntimePermissions;

@RuntimePermissions
public class EstablishActiveActivity extends BaseActivity implements EstablishActiveContract.View, View.OnClickListener {
    private static final String TAG = EstablishActiveActivity.class.getSimpleName();
    @Inject
    StandardDialog mStandardDialog;
    @BindView(R.id.head_title)
    TextView mHeadTitle;
    
    protected String[] locationPermissions = {Manifest.permission.ACCESS_COARSE_LOCATION,       Manifest.permission.ACCESS_FINE_LOCATION};
    private static final int GPS_REQUEST_CODE = 2000;
    private double longitude;
    private double latitude;

    @Override
    protected int getContentViewID() {
        return R.layout.activity_establish_active;
    }

    @Override
    protected void injectDagger() {
        activityComponent().inject(this);
    }

    @Override
    protected void initViewsAndEvents() {
        mActivePresenter.attachView(this);
        mHeadTitle.setText(getString(R.string.establish_create_active));
    }

@OnClick(R.id.establish_exercise_location_layout)
public void onViewClicked(View view) {
    switch (view.getId()) {
        case R.id.establish_exercise_location_layout:
            SoftInputManager.closeSoftInput(this, mTvLocation);
            if (!checkPermissions(mContext, locationPermissions)) {//是否有定位权限
                EstablishActiveActivityPermissionsDispatcher.getLocationWithPermissionCheck(this);
                return;
            }
            if (!isGPSOpen(mContext)) {//是否打开GPS
                mStandardDialog.show();
                mStandardDialog.setTitle(getString(R.string.permission_title));
                mStandardDialog.setContent(getString(R.string.permission_location));
                mStandardDialog.setOk(getString(R.string.goto_set));
                mStandardDialog.setCancel(getString(R.string.cancel));
                mStandardDialog.setOnDialogClickListener(new StandardDialog.OnDialogClickListener() {
                    @Override
                    public void btnOkClick() {
                        //跳转GPS设置界面
                        Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                        startActivityForResult(intent, GPS_REQUEST_CODE);
                    }

                    @Override
                    public void btnCancelClick() {
                    }
                });
                return;
            }
            MapPointActivity.actionStart(this);
            break;
    }
}

    /**
     * 权限操作   定位权限
     * 相关操作在@NeedsPermission，@OnPermissionDenied，@OnNeverAskAgain中都有
     */
    //获取权限
    @NeedsPermission({Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION})
    void getLocation() {//同意权限
    }

    //拒绝权限
    @OnPermissionDenied({Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION})
    void getLocationDenied() {
        if (!mStandardDialog.isShowing()) {
            mStandardDialog.show();
            mStandardDialog.setTitle(getString(R.string.permission_title));
            mStandardDialog.setContent(getString(R.string.permission_location));
            mStandardDialog.setOk(getString(R.string.goto_set));
            mStandardDialog.setCancel(getString(R.string.cancel));
            mStandardDialog.setOnDialogClickListener(new StandardDialog.OnDialogClickListener() {
                @Override
                public void btnOkClick() {
                    JumpPermissionUtil.SystemConfig(EstablishActiveActivity.this);
                }

                @Override
                public void btnCancelClick() {
                }
            });
        }
    }

    //不在提醒权限
    @OnNeverAskAgain({Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION})
    void externalLocationNever() {
        if (!mStandardDialog.isShowing()) {
            mStandardDialog.show();
            mStandardDialog.setTitle(getString(R.string.permission_title));
            mStandardDialog.setContent(getString(R.string.permission_location));
            mStandardDialog.setOk(getString(R.string.goto_set));
            mStandardDialog.setCancel(getString(R.string.cancel));
            mStandardDialog.setOnDialogClickListener(new StandardDialog.OnDialogClickListener() {
                @Override
                public void btnOkClick() {
                    JumpPermissionUtil.SystemConfig(EstablishActiveActivity.this);
                }

                @Override
                public void btnCancelClick() {
                }
            });
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        // 注意：将权限处理委托给生成的方法。
        EstablishActiveActivityPermissionsDispatcher.onRequestPermissionsResult(this, requestCode, grantResults);
    }
}

/**
 * 检查权限是否开启
 */
public static boolean checkPermissions(Context context, String[] permissions) {
    for (String permission : permissions) {
        if (ContextCompat.checkSelfPermission(context, permission)
                != PackageManager.PERMISSION_GRANTED) {
            return false;
        }
    }
    return true;
}

/**
 * 判断GPS是否开启，GPS或者AGPS开启一个就认为是开启的
 *
 * @return true 表示开启
 */
public static boolean isGPSOpen(final Context context) {
    LocationManager locationManager
            = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    if (locationManager != null) {
        // 通过GPS卫星定位，定位级别可以精确到街（通过24颗卫星定位，在室外和空旷的地方定位准确、速度快）
        boolean gps = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        // 通过WLAN或移动网络(3G/2G)确定的位置（也称作AGPS，辅助GPS定位。主要用于在室内或遮盖物（建筑群或茂密的深林等）密集的地方定位）
        boolean network = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
        if (gps || network) {
            return true;
        }
    }
    return false;
}

4.EstablishActiveActivityPermissionsDispatcher类需要如下图操作才可以对应生成，规则是当前类名+PermissionsDispatcher。
