权限工具activity：

public class BaseActivity extends AppCompatActivity {    public String[] permissions = new String[]{ //申请的权限            Manifest.permission.WRITE_EXTERNAL_STORAGE,            Manifest.permission.READ_EXTERNAL_STORAGE,            Manifest.permission.BODY_SENSORS,            Manifest.permission.ACCESS_COARSE_LOCATION,            Manifest.permission.ACCESS_FINE_LOCATION};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);    }    /**     * 判断系统版本是否是Android6.0以上     * @return     */    protected boolean isSystemVersionLarge23(){        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {            return true;        }else {            return false;        }    }    /**     * 检查多个权限是否被授予     * @param permissions 被检查权限名     * @return     */    protected boolean checkMorePermission(String[] permissions){        boolean isAllCheck = false;        for (int i = 0; i < permissions.length; i++) {            if (ContextCompat.checkSelfPermission(this,permissions[i]) != PackageManager.PERMISSION_GRANTED){                isAllCheck = true;                break;            }        }        if (isAllCheck){            return false;        }else {            return true;        }    }    /**     * 检查单个权限是否被授予     * @param permission 被检查权限名     * @return     */    protected boolean checkOnePermission(String permission){        if (ContextCompat.checkSelfPermission(this,permission) != PackageManager.PERMISSION_GRANTED){            return false;        }else{            return true;        }    }    /**     * 请求权限一个或多个     * @param permissions     * @param requestCode     */    protected void requestOneOrMorePermissions(String[] permissions,int requestCode,AppCompatActivity activity){        boolean isAllCheck = false;        for (int i = 0; i < permissions.length; i++) {            if (!checkOnePermission(permissions[i])){                isAllCheck = true;                break;            }        }        if (isAllCheck){            ActivityCompat.requestPermissions(activity,permissions,requestCode);        }    }    /**     * 获取应用版本号     * @return     * @throws PackageManager.NameNotFoundException     */    protected float getVersionCode(){        float versionCode = 0;        try {            versionCode = getPackageManager().getPackageInfo(getPackageName(),0).versionCode;        } catch (PackageManager.NameNotFoundException e) {            e.printStackTrace();        }        return versionCode;    }    public void requestSDcardPermission(AppCompatActivity activity,int resultcode){        //检查SDcard权限        if (activity.checkCallingOrSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED                && activity.checkCallingOrSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED){            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE},resultcode);        }    }    public void requestSensorPermission(AppCompatActivity activity,int resultcode){        //检查传感器权限        if (activity.checkCallingOrSelfPermission(Manifest.permission.BODY_SENSORS) != PackageManager.PERMISSION_GRANTED){            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.BODY_SENSORS},resultcode);        }    }    public void requestPositionPermission(AppCompatActivity activity,int resultcode){        //检查位置权限        if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED                && ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION},resultcode);        }    }}

继承Baseactivity一次请求多个权限：

public class LauchActivity extends BaseActivity {       @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.lauch_activity);        //判断系统版本是否是6.0        if (isSystemVersionLarge23()){            checkPermission();        }else {            prepare();        }    }    private void prepare(){ //操作    }    private void checkPermission(){        if (checkMorePermission(permissions)){                prepare();        }else {            requestOneOrMorePermissions(permissions,11,this);//一次请求多个权限        }    }    //申请权限回调  Android6.0以上才会调用     @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        switch (requestCode){            case 11:                if (grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){                    //所有权限通过才会                    prepare();                }else {                    //拒绝一个就会这出现                    showHintDialog("获取权限失败！");                }                break;        }    }    /**     * 拒绝权限弹出提示     * @param messege     */    protected void showHintDialog(String messege){        AlertDialog dialog = new AlertDialog.Builder(this).create();        dialog.setMessage(messege);        dialog.setButton(DialogInterface.BUTTON_POSITIVE, "授权", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                checkPermission();                dialog.dismiss();            }        });        dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "退出", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                finish();                dialog.dismiss();            }        });        dialog.show();    }}

继承Baseactivity一次请求一个权限：

requestSDcardPermission(this,111);requestSensorPermission(this,112);requestPositionPermission(this,113);/** * Android6.0以上动态权限回调 * @param requestCode * @param permissions * @param grantResults */@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    switch (requestCode){        case 111:            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){                //权限通过            }else {                //拒绝一个就会这出现                            }            break;        case 112:            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){                //权限通过            }else {                //拒绝一个就会这出现                            }            break;        case 113:            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){                //所有权限通过才会            }else {                //拒绝一个就会这出现                            }            break;        default:            super.onRequestPermissionsResult(requestCode,permissions,grantResults);            break;    }}
