如何使用自己的动作监听器在 Android Studio 中创建复选框 object

Question

I already did it on java on which the JCheckbox object has it's own Action Listener and characteristics, here is a sample code in java..

private class checkBoxTask extends JCheckBox{

    checkBoxTask me;

    public checkBoxTask(){
        super();
        me = this;
        me.setText("task");
  }
}

But at Android Studio, I'm getting a 'super(Context context)' constructor that gave an error on adding the checkbox in the layout because i need to pass an argument value on it which is i don't know what.

class task extends androidx.appcompat.widget.AppCompatCheckBox {

    task me;

    public task(Context context) {
        super(context);
        me=this;
        me.setText("task");
    }
  }

FloatingActionButton newTask = findViewById(R.id.newTask);

    newTask.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {

            LinearLayout taskLayout = findViewById(R.id.taskLayout);
            taskLayout.addView(new task()); //<-- here is where the 
   code wants me to put an argument
            logValue++;
        }
    });

Im still new to this, I'd like to know what can I do in that constructor

Answer 1

It looks like you need to pass a Context argument (https://developer.android.com/reference/android/content/Context ).

For example in fragment, you should get it like this:

Context mContext; // global variable

@Override
public void onAttach(@NonNull Context context) {
    super.onAttach(context);
    mContext = context;
}

Or you can simply do this:

taskLayout.addView(new task(getContext));

I figured it out now. thanks for Etoile., I just pass the java class name as the context. here..

public void onClick(View view) {

            LinearLayout taskLayout = findViewById(R.id.taskLayout);
            taskLayout.addView(new task(MainActivity.this));
            logValue++;
        }
