Fragment中使用onActivityResult

使用场景：

ActivityA中含有Fragment A在FragmentA中跳转到ActivityB中。这个时候onActivityResult是无效的，没有执行到。

解决方案：

在BaseActivty中添加如下代码 (Base类要继承FragmentActivity) 添加完之后发现 Fragment中的onActivityResult生效了

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

System.out.println("BaseActivity onActivityResult");

FragmentManager fragmentManager = getSupportFragmentManager();

for (int i = 0; i < fragmentManager.getFragments().size(); i++) {

Fragment fragment = fragmentManager.getFragments().get(i);

if (fragment == null) {

FontLog.i(getClass(), Integer.toHexString(requestCode));

} else {

handleResult(fragment, requestCode, resultCode, data);

}

}

}

private void handleResult(Fragment fragment, int requestCode, int resultCode, Intent data) {

fragment.onActivityResult(requestCode, resultCode, data);//调用每个Fragment的onActivityResult

List childFragment = fragment.getChildFragmentManager().getFragments(); //找到第二层Fragment

if (childFragment != null)

for (Fragment f : childFragment)

if (f != null) {

handleResult(f, requestCode, resultCode, data);

}

if (childFragment == null) {

FontLog.i(getClass(), "MyBaseFragmentActivity is null");

} }
