Mobile security defender 06-Mobile Anti-Theft custom dialog box

Modify the titlebar of the main interface

You can modify the corresponding configuration in the system's Androidmanifest.xml file to change the theme of the main interface (set to no titlebar style)

The current main interface style is:

        <activity android:name= "com.liuhao.mobilesafe.ui.MainActivity"            android:theme= "@android: style/ Theme.notitlebar "            android:label=" @string/main_screen ">        </activity>

After setting the style to:

Add a custom title and add the appropriate text directly to the top of the main interface layout, as follows:

    <linearlayout         android:layout_width= "match_parent"        android:layout_height= "40dip"        android: background= "@drawable/title_background"        android:gravity= "center_horizontal|center_vertical"        android:o rientation= "vertical"        >        <textview             android:layout_width= "wrap_content"            android:layout_ height= "Wrap_content"            android:textcolor= "@color/textcolor"            android:textsize= "22SP"            android:text = "Cottage phone Guardian"            />    </LinearLayout>

It also adds a title_background background:

<?xml version= "1.0" encoding= "Utf-8"? ><shape xmlns:android= "Http://schemas.android.com/apk/res/android"     android:shape= "Rectangle"    >    <!--border--    <stroke        android:width= "0.5dip"        Android:color= "#ff505050"        />        <!--specify Corners--    <corners         android:radius= "2dip"        / >        <!--gradient--    <gradient         android:startcolor= "#ff505050"        android:centercolor= "# ff383030 "        android:endcolor=" #ff282828 "/></shape>

Add after Effect:

From the main interface click on the activation diagram to switch to live phone anti-theft interface

@Override public    void Onitemclick (adapterview<?> parent, view view, int position,            long id) {        log.i ( TAG, "Click on location" + position);        Switch (position) {case        0:            log.i (TAG, "Enter mobile phone anti-theft");            Intent lostintent = new Intent (mainactivity.this, lostprotectedactivity.class);            StartActivity (lostintent);            break;        }    }

After the icon is hidden, the user can dial a number in the dial-up interface to enter the mobile phone anti-theft interface (Knowledge Point: Broadcast) to get the broadcast sent by the system

• Callphonereceiver: In the broadcast recipient, after receiving the corresponding processing

• Configuring the System receiver Androidmanifest.xml:

    <receiver android:name= "Com.liuhao.mobilesafe.receiver.CallPhoneReceiver" >        <intent-filter android: priority= ">            <action android:name=" Android.intent.action.NEW_OUTGOING_CALL "/>        </ Intent-filter>    </receiver>

• Configure permissions: Android.permission.PROCESS_OUTGOING_CALLS, reset the path of the outgoing call

<uses-permission android:name= "Android.permission.PROCESS_OUTGOING_CALLS"/>

Exception handling:

Failed to activate the target activity, the program terminated abnormally.

Unable to start receiver Com.liuhao.mobilesafe.receiver.CallPhoneReceiver:android.util.AndroidRuntimeException: Calling StartActivity () from outside of an Activity context requires the Flag_activity_new_task FLAG. Is this really what do you want?

In an ACTIVITY stack out of the startactivity () operation, the specified flag_activity_new_task flag must be displayed for the intent.

Analysis: We are activating a activity,activity in a broadcast receiver is running in the task stack, while the broadcast receiver is not in the task stack. Therefore, activating an activity in a broadcast recipient or service must specify the FLAG_ACTIVITY_NEW_TASK flag, which specifies that the activity to be activated runs in its own task stack.

<pre name= "code" class= "Java" >lostintent.setflags (Intent.flag_activity_new_task)

• Callphonereceiver.java the complete

Equals (number)) {            Intent lostintent = new Intent (context, lostprotectedactivity.class);            Specifies that the ACTIVITY to be activated runs            lostintent.setflags (intent.flag_activity_new_task) in its own task stack;            Context.startactivity (lostintent);            Terminate this dial-up            //cannot terminate            setresultdata (null) through Abortbroadcast ();}        }}
