Question

CreateTimerActivity.java

@Override 
protected void onCreate(Bundle savedInstanceState) {

    mVisible = true; 
    mControlsView = findViewById(R.id.create_timer_content_controls); 
    mContentView = findViewById(R.id.create_timer_content); 


    // Set up the user interaction to manually show or hide the system UI. 
    mContentView.setOnClickListener((View view) -> { 
     toggle(); 
    }); 

    /*XmlPullParser parser = getResources().getXml(R.id.view_tim); 
    AttributeSet attributes = Xml.asAttributeSet(parser);*/

Answer 1

J'ai eu cette question et je l'ai résolu dans cette façon ...

• Ne pas appeler une instance de CustomView ou même vars statiques de l'activité.
• seulement définir constructeur avec (Contexte, Attributs)
• et initialiser tout ce que vous voulez dans la classe customView.

Bonne chance
