openOptionsMenu（）不工作

Question

好吧，試了很多方法來解決這個問題，但沒有...我想通過菜單項打開選項菜單。

package com.example.tachles; 

import android.content.Intent; 
import android.net.Uri; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuInflater; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.ImageView; 
import android.widget.ShareActionProvider; 


public class MainActivity extends AnimActivity { 

    private ShareActionProvider mShareActionProvider; 
    ImageView history, contact, info, share; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     history = (ImageView) findViewById(R.id.imageView2); 
     history.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 

       Intent history = new Intent(getApplicationContext(), 
         HistoryMenu.class); 
       startActivity(history); 
      } 
     }); 

     contact = (ImageView) findViewById(R.id.imageView8); 
     contact.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       String recepientEmail = "mirnax.info@gmail.com"; 
       Intent intent = new Intent(Intent.ACTION_SENDTO); 
       intent.setData(Uri.parse("mailto:" + recepientEmail)); 

       startActivity(intent); 

      } 
     }); 

     info = (ImageView) findViewById(R.id.imageView9); 
     info.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 

       Intent info = new Intent(getApplicationContext(), Odot.class); 
       startActivity(info); 

      } 
     }); 
    } 

    // Menu 
    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.actionbar, menu); 

     // Get the ActionProvider for later usage 
     mShareActionProvider = (ShareActionProvider) menu.findItem(
       R.id.action_share).getActionProvider(); 

     /** Setting a share intent */ 
     mShareActionProvider.setShareIntent(getDefaultShareIntent()); 

     return super.onCreateOptionsMenu(menu); 
    } 

    private Intent getDefaultShareIntent() { 
     Intent intent = new Intent(Intent.ACTION_SEND); 
     intent.setType("text/plain"); 
     intent.putExtra(Intent.EXTRA_SUBJECT, 
       "תכל'ס - האפליקציה שתלווה אותך לבגרויות"); 
     intent.putExtra(Intent.EXTRA_TEXT, 
       "https://play.google.com/store/apps/details?id=com.tachles"); 
     return intent; 
    } 


    public void Options(MenuItem item){ 

     MainActivity.this.openOptionsMenu(); 
     } 

    public void like(MenuItem item) { 
     switch (item.getItemId()) { 
     case R.id.action_like: 
      Uri uri = Uri.parse("https://m.facebook.com/tachles.mirnax?_rdr"); 
      Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
      startActivity(intent); 
     } 

    } 



} 

也試過這種方式，它只是什麼也不做...... Android Option Menu on Button click

請幫助...沒有錯誤，沒有logcat的......

下面覆蓋的方法用於創建上下文菜單視圖。

@Override 
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) 
    { 
     super.onCreateContextMenu(menu, v, menuInfo); 
     menu.add(0, 1, 0, "Menu 1"); 
     menu.add(0, 2, 0, "Menu 2"); 
     menu.add(0, 3, 0, "Menu 3"); 
    } 

使用下面覆蓋的方法來處理活動代碼中的點擊偵聽器。

@Override 
    public boolean onContextItemSelected(MenuItem item) 
    { 

     switch (item.getItemId()) 
     { 
     case 1: 
      //do your code here 
      break; 
     case 2: 
      //do your code here 
      break; 
     case 3: 
      //do your code here 
      break; 
     default : break; 
      } 

在你onCreateView()就叫registerForContextMenu(yourButton);並具有YourClassName.this.openContextMenu(v);
