Intent页面跳转工具类分享

将常用的页面跳转做了下封装，方便使用。

源码

public class IntentUtils {

    private static volatile IntentUtils sInstance = null;

    private IntentUtils() {

    }

    public static IntentUtils getDefault() {
        if (null == sInstance) {
            synchronized (IntentUtils.class) {
                if (null == sInstance) {
                    sInstance = new IntentUtils();
                }
            }
        }
        return sInstance;
    }

使用方法

由当前Activity跳转目标Activity

IntentUtils.getDefault().startActivity(
                    this,
                    TargetActivity.class);

由当前Activity跳转目标Activity，携带数据（只封装了Bundle）

IntentUtils.getDefault().startActivity(
                    this,
                    TargetActivity.class,
                    bundle);

由当前Activity跳转目标Activityy，携带数据（只封装了Bundle）和请求码

IntentUtils.getDefault().startActivity(
                    this,
                    TargetActivity.class,
                    bundle,
                    REQUEST_CODE);

销毁当前Activity并携带结果码

IntentUtils.getDefault().finishForResult(
                this,
                RESULT_CODE);

销毁当前Activity并携带数据（只封装了Bundle）和结果码

IntentUtils.getDefault().finishForResult(
                this,
                bundle
                RESULT_CODE);

在当前Activity接收Intent的数据（只封装了Bundle）

IntentUtils.getDefault().getIntentBundle(this);

其它
