Im trying to make a menu that will control the fragments – the screens. (just like in instagram),<\/p>\n

But it crashes:<\/p>\n

The code of the main activity:<\/p>\n

public class All extends Activity {\n\n    Button map;\n    Button add;\n\n    View MapFragment;\n    View AddFragment;\n\n    @Override\n    protected void onCreate(Bundle savedInstanceState) {\n        super.onCreate(savedInstanceState);\n        setContentView(R.layout.activity_all);\n\n        map=(Button)findViewById(R.id.map);\n        add=(Button)findViewById(R.id.add);\n\n        MapFragment=(View)findViewById(R.id.MapFragment);\n        AddFragment=(View)findViewById(R.id.AddFragment);\n\n        MapFragment.bringToFront();\n\n        map.setOnClickListener(new OnClickListener() {\n            public void onClick(View v) {\n                MapFragment.bringToFront();\n            }\n        });\n\n        add.setOnClickListener(new OnClickListener() {\n            public void onClick(View v) {\n                AddFragment.bringToFront();\n            }\n        });\n    }\n<\/code><\/pre>\n
