ZPermissions

在项目中使用方法：

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

dependencies {
	implementation 'com.github.zhufui:ZPermissions:1.0.2'
}

如果出现support包冲突可以采用下面方式将冲突的包去除

dependencies {
	implementation ('com.github.zhufui:ZPermissions:1.0.2'){
    exclude group:'com.android.support'
    }
}

使用方法：
requestCode写在一个单独的类中

public class PermissionReqCode {
    public static final int CODE0 = 0;
}

请求权限：

ZPermissions.requestPermissions(MainActivity.this,
                PermissionReqCode.CODE0, MainActivity.this, PermissionGroup.build(
                        PermissionGroup.CAMERA()
                ));

在destory中取消回调

@Override
protected void onDestroy() {
    super.onDestroy();
    ZPermissions.recycleCallback();
}

在onRequestPermissionsResult中的写法：

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    ZPermissions.onRequestPermissionsResult(requestCode, grantResults);
}

同意/拒绝权限：

@Override
public void permissionGrant(int requestCode) {
    if (requestCode == PermissionReqCode.CODE0) {
        Toast.makeText(this, "相机", Toast.LENGTH_SHORT).show();
        return;
    }
    if (requestCode == PermissionReqCode.CODE1) {
        Toast.makeText(this, "sd卡", Toast.LENGTH_SHORT).show();
    }
}

@Override
public void permissionDenied(int requestCode) {
    Toast.makeText(this, "请去设置->应用->" + getString(R.string.app_name) + "->权限,打开权限", Toast.LENGTH_SHORT).show();
}
