Cocos2d-x Jni c ++ java Intermodulation and refreshing each other UI controls the simplest example (below)

 

 

C ++ calls java:

 

C ++ calls java. Colleagues refreshed the android Edit View Control

 

 

Step 1:

Step 2: Create a layout File

Step 3:

 

Public static EditText myView;

Step 4: Add a text input box

 

LayoutInflater inflater = (LayoutInflater) getSystemService (Context. LAYOUT_INFLATER_SERVICE );

MyView = (EditText) LayoutInflater. from (this). inflate (R. layout. myedit, framelayout, false );

MyView. addTextChangedListener (watcher );

MyView. setMovementMethod (ScrollingMovementMethod. getInstance ());

 

Framelayout. addView (myView );

 

 

Step 5: Add a listener

 

 

TextWatcher watcher = new TextWatcher ()

{

 

@ Override

Public void afterTextChanged (Editable s)

{

// TODO Auto-generated method stub

Log. d (TAG, 111111 );

}

 

@ Override

Public void beforeTextChanged (CharSequence s, int start, int count, int after)

{

// TODO Auto-generated method stub

Log. d (TAG, 22222 );

}

 

@ Override

Public void onTextChanged (CharSequence s, int start, int before, int count)

{

Log. d (TAG, 33 = [TextWatcher] [onTextChanged] + s );

}

 

};

Step 6:

Public static void hideAdView (String [] str)

{

MHandler. obtainMessage (100, str). sendToTarget ();

}

 

Private static HandlermHandler = new Handler ()

{

Public void handleMessage (Message msg)

{

Switch (msg. what)

{

Case 100: // UPDATE_UI:

{

String [] arrStrings = (String []) msg. obj;

If (arrStrings [0]. equals (I'm a tititile ))

{

TestJni. this. myView. setText (C ++ Change Java EditView string Test !);

}

}

Break;

Default:

Break;

}

}

};

 

 

Supplement:

// MyView. setBackgroundColor (Color. TRANSPARENT); // the background Color is TRANSPARENT.

// Framelayout. removeView (myView); // remove the control

 

 

 

C ++ code

 

# If (CC_TARGET_PLATFORM = CC_PLATFORM_ANDROID)

# Include platform/android/jni/JniHelper. h

Void HelloWorld: goJava ()

{

JniMethodInfo jmi;

If (JniHelper: getStaticMethodInfo (jmi, org/cocos2dx/TestJni, hideAdView, ([Ljava/lang/String;) V ))

{

Jclass str_cls = jmi. env-> FindClass (java/lang/String );

 

Jstring str1 = jmi. env-> NewStringUTF (I'm a titile );

Jstring str2 = jmi. env-> NewStringUTF (Are yor exit game ?);

 

JobjectArray arrs = jmi. env-> NewObjectArray (2, str_cls, 0 );

Jmi. env-> SetObjectArrayElement (arrs, 0, str1 );

Jmi. env-> SetObjectArrayElement (arrs, 1, str2 );

Jmi. env-> CallStaticVoidMethod (jmi. classID, jmi. methodID, arrs );

}

}

# Endif

Then call

 

# If (CC_TARGET_PLATFORM = CC_PLATFORM_ANDROID)

GoJava ();

# Endif

 

Finally, compile c ++ and android
