Question

我创建了一个Android应用程序并且卡住了！

无论我尝试什么，我无法解决它。

它确实像一个非按钮。

我的片段活动代码是

public class Home extends FragmentActivity {

    ActionBar action;

    Typeface tf1;
    TextView icindekiler;
    TextView tv1;
    TextView tv2;
    TextView tv3;
    TextView tv4;
    TextView tv5;
    TextView tv6;
    Fragment fragment = null;


    ViewPager viewPager;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.home_);


        viewPager=(ViewPager)findViewById(R.id.pager1);

        FragmentManager fm=getSupportFragmentManager();

        viewPager.setAdapter(new MyAdapter(fm));


    }

    class MyAdapter extends FragmentPagerAdapter{
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {



            if(position==0)
                fragment= new Home1();




            if(position==1)
                fragment=new Home2();
            return fragment;
        }

        @Override
        public int getCount() {
            return 2;
        }
    }

}

和我的第一片段是

public class MainActivity extends Fragment {



    ImageButton btn;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View viewMain=inflater.inflate(R.layout.activity_main,container,false);

        btn=(ImageButton)viewMain.findViewById(R.id.calisanbtn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(), "You Clicked the button!", Toast.LENGTH_LONG).show();
                Intent i=new Intent(getActivity(),Sunus.class);
                startActivity(i);
            }
        });
        //actionBar gizleme
        //android.support.v7.app.ActionBar action=getActivity().getSupportActionBar();
        //action.hide();





        return viewMain;
    }


    }

以及我的片段Activity and Fragment XML

图像按钮中的XML

<ImageButton
                android:layout_width="110dp"
                android:layout_height="100dp"
                android:src="@drawable/opet_sunus"
                android:id="@+id/kurumsalbtn"
                android:background="@drawable/mybutton"
                android:layout_marginRight="20dp"
                android:scaleType="fitCenter"
                android:padding="5dp"

                />

最后一次认为我在View页面中的Fagment活动可能是我做错了。

 <android.support.v4.view.ViewPager
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:id="@+id/pager1"
    >

</android.support.v4.view.ViewPager>

我无法解决它，任何人都可以帮助我吗？ Thnx很多：）

Answer 1

我认为你的错误是你的ImageButton id。在您的片段中，您设置了ID calisabtn

btn=(ImageButton)viewMain.findViewById(R.id.calisanbtn);

但在你的xml中声明为id kurumsalbtn

<ImageButton
                android:layout_width="110dp"
                android:layout_height="100dp"
                android:src="@drawable/opet_sunus"
                android:id="@+id/kurumsalbtn" <----
                android:background="@drawable/mybutton"
                android:layout_marginRight="20dp"
                android:scaleType="fitCenter"
                android:padding="5dp"

                />

图像按钮在片段中不起作用
