自定義 ListView 中的彈出菜單

Question

我想要達到的目標：

我有一個自定義 ListView 適配器。 我想為每個 Listitem 添加一個彈出菜單，與當前 Google Play 應用程序中的 ListView 非常相似。

這是我嘗試過的：我的大部分代碼來自這個 Android 示例samples\\android-19\\ui\\ActionBarCompat-ListPopupMenu

CustomFragmentPageAdapter.java ：

// create new fragment
mCustomFragment = CustomFragment.newInstance(position);

自定義片段.java

public class CustomFragment extends ListFragment implements View.OnClickListener{

...

@Override
public void onClick(final View v) {
    v.post(new Runnable() {
        @Override
        public void run() {
            showPopupMenu(v);
        }
    });
}

private void showPopupMenu(View view) {

    PopupMenu popup = new PopupMenu(getActivity(), view);

    popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());

    popup.show();
}

自定義陣列適配器：

public class CustomAdapter extends ArrayAdapter<WatchListPlayerItem> {
    ...    
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final int pos = position;

        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        final View rowView = inflater.inflate(R.layout.watch_list_row, parent, false);

        View popupButton = rowView.findViewById(R.id.imgPopUp);

        popupButton.setTag(getItem(position));

        popupButton.setOnClickListener(mFragment);

        return rowView;
    }
}

popup_menu.xml ：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/install"
        android:title="Install" />
    <item
        android:id="@+id/addtowishlist"
        android:title="Add to wishlist" />
</menu>

日志輸出：

java.lang.RuntimeException: Failed to resolve attribute at index 6
            at android.content.res.TypedArray.getLayoutDimension(TypedArray.java:603)
            at android.view.ViewGroup$LayoutParams.setBaseAttributes(ViewGroup.java:6423)
            at android.view.ViewGroup$MarginLayoutParams.<init>(ViewGroup.java:6591)
            at android.widget.FrameLayout$LayoutParams.<init>(FrameLayout.java:735)
...

該錯誤在我的 CustomFragment 中的 popup.show() 處引發。

這個錯誤顯然讓我發瘋，非常感謝任何幫助解決這個問題！

Answer 1

我終於找到了我的問題的解決方案，盡管我沒有解釋為什么這個解決方案有效。

使用以下導入我總是有錯誤：

import android.support.v7.widget.PopupMenu;

它可以正常使用以下導入：

import android.widget.PopupMenu;

我測試了Ric提供的代碼（感謝您的幫助！）和我自己的代碼。 兩者現在都在運作。 也許某人有解釋為什么導入在這種情況下很重要。

Answer 2

首先在custom-item-listview.xml中創建一個button ，然后添加以下代碼：

Button ：

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button_text"
android:id="@+id/button1"
... />

類：

public class CustomAdapter extends ArrayAdapter<CustomItem> {

    private static Activity context = null;
    private final ArrayList<CustomItem> mItemsArrayList;
    private CustomFragment mFragment;


    public CustomAdapter(Activity context, ArrayList<CustomItem> itemsArrayList, CustomFragment fragment) {

        super(context, R.layout.watch_list_row, itemsArrayList);

        CustomAdapter.context = context;
        this.mItemsArrayList = itemsArrayList;
        this.mFragment = fragment;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final int pos = position;
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        final View rowView = inflater.inflate(R.layout.watch_list_row, parent, false);
    final Button popUp_btn = (Button)rowView.findViewById(R.id.button1);
    popUp_btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            final PopupMenu popup = new PopupMenu(context, popUp_btn);
            popup.getMenuInflater().inflate(R.menu.context_menu, popup.getMenu());
            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                public boolean onMenuItemClick(MenuItem item) {
                    int i = item.getItemId();
                    if (i == R.id.item1) {
                        //do something
                        return true;
                    }
                    else if (i == R.id.item2){
                        //do something
                        return true;
                    }
                    else if (i == R.id.item3) {
                        //do something
                        return true;
                    }
                    else {
                        return onMenuItemClick(item);
                    }
                }
            });

            popup.show();

編輯：這適合我：

TAB1

public  class TAB1 extends Fragment {
View view;

public TAB1() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.tab1, null);


            ListView list = (ListView) view.findViewById(android.R.id.list);
            CustomList adapter = new CustomList(getActivity());
            adapter.addAll();
            list.setAdapter(adapter);


    return view;
}

CustomList ：

public class CustomList extends ArrayAdapter<YourArrayAdapter> {

private static Activity context = null;

public CustomList(Activity context) {
    super(context, R.layout.custom_listview, web);
    CustomList.context = context;
}
@Override
public View getView(final int position, View view, ViewGroup parent) {
    LayoutInflater inflater = context.getLayoutInflater();
    final View rowView = inflater.inflate(R.layout.custom_listview, null, true);

    //your stuff here

    final Button popUp_btn = (Button)rowView.findViewById(R.id.button1);
    popUp_btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            final PopupMenu popup = new PopupMenu(context, popUp_btn);
            popup.getMenuInflater().inflate(R.menu.context_menu, popup.getMenu());
            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                public boolean onMenuItemClick(MenuItem item) {
                    int i = item.getItemId();
                    if (i == R.id.item1) {
                        //do something
                        return true;
                    }
                    else if (i == R.id.item2){
                        //do something
                        return true;
                    }
                    else if (i == R.id.item3) {
                        //do something
                        return true;
                    }
                    else {
                        return onMenuItemClick(item);
                    }
                }
            });

            popup.show();

        }
    });

    return rowView;

}

Answer 3

將此用作（活動上下文） 而非應用程序上下文或上下文

     PopupMenu popup = new PopupMenu(this, v);

Answer 4

    popup = (Button)findViewById(R.id.button);

    popup.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PopupMenu popup = new PopupMenu(MainActivity.this,view);
            popup.getMenuInflater().inflate(R.menu.popup_menu,popup.getMenu());
            popup.show();
            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {
                    int id = item.getItemId();
                    if(id==R.id.install){
                        show_toast("Install Clicked");
                    }else{
                        show_toast("WishList Clicked");                            
                    }
                    return true;
                }
            });
        }
    });



    public void show_toast(String message){
        Toast.makeText(this,message,Toast.LENGTH_SHORT).show();
    }

注意：
別忘了導入這個....

import android.support.v7.widget.PopupMenu;
import android.view.MenuItem;

Answer 5

只要您導入以下內容，Rick的行代碼就可以完美運行：

import android.widget.PopupMenu;

不是下面那個：

import android.support.v7.widget.PopupMenu;

Answer 6

當我修改主題父樣式時，我遇到了同樣的問題：來自

<style name="MainAppTheme" parent="@style/Theme.AppCompat.Light">

至

<style name="MainAppTheme" parent="@style/Theme.Base.AppCompat.Light">

也許您的應用程序使用Theme.Base樣式，該樣式未定義PopupMenu使用的所需第6個參數。 從SO問題如何在Theme.Material中使用ActionBarActivity ，Theme.AppCompat擴展了Theme.Base.AppCompat

Answer 7

我通過將參數作為靜態活動傳遞來修復類似的錯誤。 例如：

static AppCompatActivity sActivity;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    sActivity = this;

yourLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        PopupMenu popup = new PopupMenu(sActivity, v);
        MenuInflater inflater = popup.getMenuInflater();
        inflater.inflate(R.menu.my_popup_menu, popup.getMenu());
        popup.show();
        }
   });
}

此外，您的問題可能是這個問題： 問題152141

希望它能幫到你，尊重android.support.v7.widget.PopupMenu導入。

問候。

Answer 8

首先需要導入
導入 android.widget.PopupMenu；

你的它一定是這樣的

holder.dayDate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PopupMenu popupMenu = new PopupMenu(context, holder.dayDate);
                popupMenu.getMenu().add("Futa");
                popupMenu.getMenu().add("Acha");
                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        switch (item.getTitle().toString()) {
                            case "View" :
                                Toast.makeText(context, "Bidhaa imefutwa.", Toast.LENGTH_SHORT).show();
                                break;
                            case "Edit":
//                                popupMenu.dismiss();
                                break;
                        }
                        return false;
                    }
                });
                popupMenu.show();
            }
        });

    }
