How To Make Analog Clock Invisible And Visible On Click Button Android

Question

i working in app and want to invisible and visible the analog clock when i click on buttons

Solution 1:

      AnalogClock clock  = (AnalogClock) v; 
      clock.setVisibility(View.GONE);

this is wrong, v is your button, not the clock. you need to just do

clock.setVisibility(View.GONE);

EDIT I've tested your code and it works:

publicclassMainActivityextendsActivity {

        @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            finalAnalogClockclock= (AnalogClock) findViewById(R.id.AnalogClock);
            Buttonshow= (Button) findViewById(R.id.show);
            Buttonhide= (Button) findViewById(R.id.hide);

            show.setOnClickListener(newView.OnClickListener() {
                @OverridepublicvoidonClick(View v) {
                    clock.setVisibility(View.VISIBLE);
                }
            });
            hide.setOnClickListener(newView.OnClickListener() {
                @OverridepublicvoidonClick(View v) {
                    clock.setVisibility(View.INVISIBLE);
                }
            });
        }

    }

And the layout:
