android - 如何在ViewPager中设置OnClickListener

Question

我是 Android 开发新手，正在学习编写和设计 Android 项目。我在使用 ViewPager 时遇到问题，无法在此站点上或通过 Google 搜索找到答案。

问题:我无法让 Button 在 ViewPager 中执行其操作。

你可以在这里看到我的项目和 apk 文件:https://dl.dropbox.com/u/9820517/ForOneTimeDownload/TestPagerView.rar

这是我的 PagerDemo.java:

 public class PagerDemo extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_pager_demo);

        myPagerAdapter adapter = new myPagerAdapter();
        ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
        myPager.setAdapter(adapter);
        myPager.setCurrentItem(2);

        SetAllBtnFunc();
    }

    public void SetAllBtnFunc() {
        //all func
        View.OnTouchListener touch = new View.OnTouchListener() {

                public boolean onTouch(View v, MotionEvent event) {
                    // TODO Auto-generated method stub
                    Log.d("hlv_trinh", "Button be Touched!");
                    return false;
                }
            };

            View.OnClickListener click = new View.OnClickListener() {

                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Log.d("hlv_trinh", "Button be Clicked!");
                }
            };

        //Get view
        View v = getLayoutInflater().inflate(R.layout.middle, null);

        Button b = (Button) v.findViewById(R.id.myBtn);
        b.setOnClickListener(click);
        b.setOnTouchListener(touch);
        }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_pager_demo, menu);
        return true;
    }
    private class myPagerAdapter extends PagerAdapter {

        public int getCount() {
            return 5;
        }

        public Object instantiateItem(View collection, int position) {

            LayoutInflater inflater = (LayoutInflater) collection.getContext()
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            int resId = 0;
            switch (position) {
            case 0:
                resId = R.layout.farleft;
                break;
            case 1:
                resId = R.layout.left;
                break;
            case 2:
                resId = R.layout.middle;
                break;
            case 3:
                resId = R.layout.right;
                break;
            case 4:
                resId = R.layout.farright;
                break;
            }

            View view = inflater.inflate(resId, null);

            ((ViewPager) collection).addView(view, 0);

            return view;
        }

        @Override
        public void destroyItem(View arg0, int arg1, Object arg2) {
            ((ViewPager) arg0).removeView((View) arg2);

        }


        @Override
        public boolean isViewFromObject(View arg0, Object arg1) {
            return arg0 == ((View) arg1);

        }

        @Override
        public Parcelable saveState() {
            return null;
        }
    }
    }

我这里的布局内容:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="Middle"
        android:textSize="30dp" >
    </TextView>

    <Button
        android:id="@+id/myBtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Test Click" />
</LinearLayout>

Answer 1

这是一个简单的解决方案。
在您的布局 XML 中，在按钮标记中设置 android:onClick="AnyName"，然后在您的 PagerDemo.java 中，放置:

public void AnyName(View v) {
    // Do your stuff
}

在 ViewPager 中设置 onClickListener。
