android - Searchview 使应用程序崩溃

Question

我使用的不是 menuItem 而是布局中的搜索 View 。我支持的最低 API 级别是 9，搜索 View 是 11。

现在我这样创建了我的搜索 View :

 <SearchView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/searchView"
        android:layout_marginBottom="1dp"/>

在直线布局中。我注意到警告，所以我将其更改为:

<android.support.v7.widget.SearchView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/searchView"
            android:layout_marginBottom="1dp"/>

但是我的应用程序在新的 Android 固件上崩溃了。

我在我的应用中这样使用它:

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchView searchView = (SearchView) findViewById(R.id.searchView);
        searchView.setOnSearchClickListener(this);
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String s) {

                return false;
            }

            @Override
            public boolean onQueryTextChange(String s) {

                FragmentManager manager = getSupportFragmentManager();
                FragmentTransaction transaction = manager.beginTransaction();
                if (s.length() == 0) {
                    transaction.show(mapFragment);
                } else {

                    transaction.hide(mapFragment);
                }

                updateListViewWithFilter(s);

                transaction.commit();

                return false;
            }
        });
    }

我总是得到这个错误:

Answer 1

我没有更改导入语句和使用支持小部件的方式。

除了搜索 View 之外，这段代码是我唯一更改的内容。

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

            android.support.v7.widget.SearchView  searchView = (android.support.v7.widget.SearchView) findViewById(R.id.searchView);
            searchView.setOnSearchClickListener(this);
            searchView.setOnQueryTextListener(new android.support.v7.widget.SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String s) {

                    return false;
                }

                @Override
                public boolean onQueryTextChange(String s) {

                    FragmentManager manager = getSupportFragmentManager();
                    FragmentTransaction transaction = manager.beginTransaction();
                    if (s.length() == 0) {
                        transaction.show(mapFragment);
                    } else {

                        transaction.hide(mapFragment);
                    }

                    updateListViewWithFilter(s);

                    transaction.commit();

                    return false;
                }
            });
        }

您可以看到我现在将 searchView 转换为 support.searchview。
