如何使用FragmentManager替代pcated的ShowDialog去$ P $ [英] How to use FragmentManager to substitute the deprecated showDialog
问题描述
我使用的方法displayDialog ......它的工作原理,但Eclipse的表明我对这个警告:
的ShowDialog(showRetry 1:0);
方法:
私人无效displayDialog(最终布尔showRetry){
mHandler.post(新的Runnable(){
公共无效的run(){
setProgressBarIndeterminateVisibility(假);
的ShowDialog(showRetry?1:0);
}
});
}
搜索我也发现了类似的问题在哪见过,现在就有的 FragmentManager 的,可以用来避免这个问题,但我不明白我怎么可以用它来修复这个问题我具体情况维持与升级Froyo和姜饼复古的兼容性。
你能帮助我吗?

您的活动应该继承 FragmentActivity
,可在的 V4支持库,你应该添加到您的项目。然后,您可以获取到 FragmentManager
使用 getSupportFragmentManager()
来显示 DialogFragment <参考/ code>。你必须创建一个
DialogFragment
的布局和你的对话需要逻辑类。下面是你期望从它显示你的 FragmentActivity
:
FragmentManager FM = getSupportFragmentManager();
YourDialogFragment yourDialog =新YourDialogFragment();
yourDialog.show(FM,some_optional_tag);
下面是一个简要介绍: HTTP://android-developers.blogspot。 COM / 2012/05 /使用-dialogfragments.html
I am using the method displayDialog... it works but Eclipse shows me a warning on this:
showDialog(showRetry ? 1 : 0);
Method:
private void displayDialog(final boolean showRetry) {
mHandler.post(new Runnable() {
public void run() {
setProgressBarIndeterminateVisibility(false);
showDialog(showRetry ? 1 : 0);
}
});
}
Searching I have found similar question in which seen that now there is the FragmentManager that can be used to avoid the problem, but I haven't understand how I could use to fix the problem in my specific scenario maintaining retro-compatibility with Froyo and GingerBread.
Could you help me?

Your activity should subclass FragmentActivity
, which can be found in the v4 support library, which you should add to your project. You then can get a reference to the FragmentManager
using getSupportFragmentManager()
to show a DialogFragment
. You'll have to create a DialogFragment
class with the layout and the logic that your dialog requires. Here's how you'd show it from your FragmentActivity
:
FragmentManager fm = getSupportFragmentManager();
YourDialogFragment yourDialog = new YourDialogFragment();
yourDialog.show(fm, "some_optional_tag");
