Android(安卓)6.0 权限适配

Launcher Activity

PermissionChecker.java

/** * 检查权限的工具类 */public class PermissionsChecker {    private final Context mContext;    public PermissionsChecker(Context context) {        mContext = context.getApplicationContext();    }    // 判断权限集合    public boolean lacksPermissions(String... permissions) {        for (String permission : permissions) {            if (lacksPermission(permission)) {                return true;            }        }        return false;    }    // 判断是否缺少权限    private boolean lacksPermission(String permission) {        return ContextCompat.checkSelfPermission(mContext, permission) ==                PackageManager.PERMISSION_DENIED;    }}

当有权限无法全部获得时，会调用showMissingPermissionDialog()方法弹出设置对话框，请根据你的实际需求判断是否需要显示。
