开始在窗口管理器新活动 [英] Start new activity in window manager
问题描述
我要开始一个新的活动，该活动对于从源实时流。当我开始的活动，它起着整个屏幕上的内容。我想在一个小屏幕，是一个surfaceview显示流的内容。我用它运行一个可运行的，因此在处理这样做。这是我怎么做的吧：
从这里 //新活动发挥
意图localIntent3 =新的意向书（android.intent.action.MAIN）;
//意图标志设置为启动新的任务在previous 1
localIntent3.setFlags（270532608）;
startActivity（localIntent3）;
在这个活动开始后，我运行在各自的处理器，这使得表面上的看法上播放的流内容的可运行。下面是我如何做到这一点：
的Runnable handlerRuntv =新的Runnable（）{
公共无效的run（）{
尝试 {
MainActivity.this.surfaceView =新SurfaceView（
MainActivity.this.getApplicationContext（））;
MainActivity.this.openSurfaceView（）;
//方法来扩展表面以更小的显示
MainActivity.this.setPipscale（）;
}赶上（例外localException）{
localException.printStackTrace（）;
}
}
};
这是我在处理程序运行：
this.handlerTV.postDelayed（handlerRuntv，300L）;
在可运行开始在处理器上运行，我做了返回preSS 在设备上要带我去了previous活动，其中的内容正在播放。
问题 ：我想直接在表面即缩放显示屏上开始活动，我不希望用户preSS后退按钮，看看流。应如何做？
**编辑：**
使用片段开始的片段活动：
//在mainactivity.java
llFragment =（的LinearLayout）findViewById（R.id.llfragment）;
FragmentTransaction T = getFragmentManager（）的BeginTransaction（）。
RunTVFragment片段=新RunFragment（）;
t.add（llFragment.getId（），片段，片段）;
t.commit（）;
// llfragment为.xml
＆LT;的LinearLayout
机器人：ID =@ + ID / llfragment
机器人：方向=横向
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT＆GT;
＆LT; / LinearLayout中＆GT;
RunFragment.java 将启动活动：
@覆盖
公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，
捆绑savedInstanceState）{
// TODO自动生成方法存根
视图V = inflater.inflate（R.layout.fragmentlayout，集装箱，假）;
返回伏;
}
@覆盖
公共无效onActivityCreated（包savedInstanceState）{
// TODO自动生成方法存根
super.onActivityCreated（savedInstanceState）;
意图localIntent3 =新的意向书（android.intent.action.MAIN）;
localIntent3.addCategory（android.intent.category.LAUNCHER）;
startActivity（localIntent3）;
this.handlerTV.postDelayed（handlerRuntv，300L）;
}
//fragmentlayout.xml
＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; RelativeLayout的的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：layout_width =match_parent
机器人：layout_height =match_parent
机器人：背景=@可绘制/后退
机器人：方向=横向＆GT;
＆LT;的FrameLayout
机器人：ID =@ + ID / surframelayout
机器人：layout_width =340dp
机器人：layout_height =280dp
机器人：layout_alignParentRight =真
机器人：layout_below =@ + ID / textView1/＆GT;
＆LT; / RelativeLayout的＆GT;
不过，活动不启动/中所要求的画面的区域的显示。相反，它开始作为一个新的任务，在previous活动。
编辑II：
NONUIFragment的定义：
@覆盖
公共无效onActivityCreated（包savedInstanceState）{
// TODO自动生成方法存根
super.onActivityCreated（savedInstanceState）;
组件名localComponentName2 =新的组件名（mstar.tvsetting.ui，mstar.tvsetting.ui.RootActivity）;
意图localIntent3 =新的意向书（android.intent.action.MAIN）;
localIntent3.addCategory（android.intent.category.LAUNCHER）;
localIntent3.setComponent（localComponentName2）;
localIntent3.setFlags（270532608）;
startActivity（localIntent3）;
this.handlerTV.postDelayed（handlerRuntv，1000L）;
}
调用 NONUI片段从 UI片段：
@覆盖
公共无效onActivityCreated（包savedInstanceState）{
// TODO自动生成方法存根
super.onActivityCreated（savedInstanceState）;
FragmentManager FM = getFragmentManager（）;
//检查，看看我们是否保留了工人的片段。
NonUITVFragment mWorkFragment =（NonUITVFragment）fm.findFragmentByTag（工作）;
//如果不保留（或第一次运行），我们需要创建它。
如果（mWorkFragment == NULL）{
mWorkFragment =新NonUITVFragment（）; //创建非UI片段实例
//告诉它是谁正在与。
mWorkFragment.setTargetFragment（此，0）;
fm.beginTransaction（）加（mWorkFragment，工作）提交（）。 //非UI片段
}
}
调用 UI片段从我的主要活动：
如果（savedInstanceState == NULL）{// UI Fragement
。getFragmentManager（）的BeginTransaction（）加（R.id.llfragment，新RunTVFragment（））提交（）。
}
我怀疑我是否理解你的问题properly.Maybe，你可以尝试使用片段没有用户界面，启动线程，而不是活动。
I want to start a new activity, the activity plays a live stream from a source. When I start the activity, it plays the content on the whole screen. I want to display the contents of the stream in a small screen which is a surfaceview. I am doing this by using a handler which runs a runnable and so on. This is how I am doing it:
//new activity played from here
Intent localIntent3 = new Intent("android.intent.action.MAIN");
//intent flag set to start a new task over the previous one
localIntent3.setFlags(270532608);
startActivity(localIntent3);
Once this activity is started, I run the runnable on the respective handler, which renders the contents played on the stream on a surface view. Here is how I do this:
Runnable handlerRuntv = new Runnable() {
public void run() {
try {
MainActivity.this.surfaceView = new SurfaceView(
MainActivity.this.getApplicationContext());
MainActivity.this.openSurfaceView();
//method to scale the surface view to a smaller display
MainActivity.this.setPipscale();
} catch (Exception localException) {
localException.printStackTrace();
}
}
};
This is how I run it on the handler:
this.handlerTV.postDelayed(handlerRuntv, 300L);
Once the runnable starts to run on the handler, I do a back press on the device to take me to the previous activity where the content is already playing.
Question: I want to start the activity directly on the scaled display of the surface i.e. I do not want the user to press the back button to see the stream. How should this be done?
**EDIT:**
Using fragments to start activity in a fragment:
//In mainactivity.java
llFragment =(LinearLayout) findViewById(R.id.llfragment);
FragmentTransaction t = getFragmentManager().beginTransaction();
RunTVFragment fragment = new RunFragment();
t.add(llFragment.getId(), fragment, "fragment");
t.commit();
//llfragment in .xml
<LinearLayout
android:id="@+id/llfragment"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</LinearLayout>
RunFragment.java that would start the activity:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View v = inflater.inflate(R.layout.fragmentlayout, container, false);
return v;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
Intent localIntent3 = new Intent("android.intent.action.MAIN");
localIntent3.addCategory("android.intent.category.LAUNCHER");
startActivity(localIntent3);
this.handlerTV.postDelayed(handlerRuntv, 300L);
}
//fragmentlayout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/back"
android:orientation="horizontal" >
<FrameLayout
android:id="@+id/surframelayout"
android:layout_width="340dp"
android:layout_height="280dp"
android:layout_alignParentRight="true"
android:layout_below="@+id/textView1"/>
</RelativeLayout>
Still, the activity does not start/display in the region of the screen required. Instead, it is started as a new task, over the previous activity..
EDIT II:
Definition of NONUIFragment:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
ComponentName localComponentName2 = new ComponentName("mstar.tvsetting.ui", "mstar.tvsetting.ui.RootActivity");
Intent localIntent3 = new Intent("android.intent.action.MAIN");
localIntent3.addCategory("android.intent.category.LAUNCHER");
localIntent3.setComponent(localComponentName2);
localIntent3.setFlags(270532608);
startActivity(localIntent3);
this.handlerTV.postDelayed(handlerRuntv, 1000L);
}
Calling NONUI-Fragment from the UI-Fragment:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
FragmentManager fm = getFragmentManager();
// Check to see if we have retained the worker fragment.
NonUITVFragment mWorkFragment = (NonUITVFragment)fm.findFragmentByTag("work");
// If not retained (or first time running), we need to create it.
if (mWorkFragment == null) {
mWorkFragment = new NonUITVFragment(); //create instance of NON UI Fragment
// Tell it who it is working with.
mWorkFragment.setTargetFragment(this, 0);
fm.beginTransaction().add(mWorkFragment, "work").commit(); //NON UI Fragment
}
}
Calling UI-Fragment from my main activity:
if (savedInstanceState == null) { //UI Fragement
getFragmentManager().beginTransaction().add(R.id.llfragment, new RunTVFragment()).commit();
}
I doubt whether i understood your question properly.Maybe you can try using a fragment without UI to initiate the thread instead of the activity.
