TextView longclick listener

Question

我做了一個TextView，我想做點什麼，當我點擊它，當我長時間點擊它。單擊工作正常，但當我長時間點擊活動關閉TextView。

這是我的代碼。

if (c.moveToFirst()) 
    { 
     do 
     { 
      final String name = c.getString(0); 
      TextView resname = new TextView(this); 
      View line = new View(this); 
      //ImageButton pin = new ImageButton(this); 

      resname.setText(c.getString(0)); 
      resname.setTextColor(Color.WHITE); 
      resname.setTextSize(30); 
      resname.setTypeface(null,Typeface.BOLD); 
      resname.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); 
      resname.setOnClickListener(new View.OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        Intent i = new Intent(); 
        if (getIntent().getStringExtra("type").contentEquals("Restaurant")){ 
         i.setClassName("com.mdl.cyrestaurants.guide", "com.mdl.cyrestaurants.guide.RestaurantDetails"); 
         i.putExtra("name",name); 
        } 
        else if(getIntent().getStringExtra("type").contentEquals("Cafe")){ 
         i.setClassName("com.mdl.cyrestaurants.guide", "com.mdl.cyrestaurants.guide.CafeDetails"); 
         i.putExtra("name",name); 
        } 
        else if(getIntent().getStringExtra("type").contentEquals("Bar")){ 
         i.setClassName("com.mdl.cyrestaurants.guide", "com.mdl.cyrestaurants.guide.BarDetails"); 
         i.putExtra("name",name); 
        } 
        startActivity(i); 
       } 
      }); 

      resname.setOnLongClickListener(new View.OnLongClickListener() { 

       @Override 
       public boolean onLongClick(View v) { 
        if(db.delpin(name)) 
         Toast.makeText(getBaseContext(), "Delete successful", Toast.LENGTH_SHORT).show(); 
        else 
         Toast.makeText(getBaseContext(), "Delete failed", Toast.LENGTH_SHORT).show(); 

        Intent i = new Intent(); 
        i.setClassName("com.mdl.cyrestaurants.guide", "com.mdl.cyrestaurants.guide.pins"); 
        i.putExtra("type", getIntent().getStringExtra("type")); 
        startActivity(i); 
        finish(); 

        return false; 
       } 
      }); 

      //pin.setImageResource(R.drawable.pin); 
      //pin.setBackgroundDrawable(getResources().getDrawable(R.drawable.unpin)); 
      //pin.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); 


      line.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,2)); 
      line.setBackgroundColor(Color.RED); 

      ((LinearLayout) layout).addView(resname); 
      //((LinearLayout) layout).addView(pin); 
      ((LinearLayout) layout).addView(line); 
     }while(c.moveToNext());

數據庫不開03-11 16：11：56.318：E/AndroidRuntime（11301）：在android.database.sqlite.SQLiteDatabase.delete（SQLiteDatabase.java:1663）

你正在嘗試做的數據庫無需打開連接即可運行

resname.setOnLongClickListener(new View.OnLongClickListener() { 

       @Override 
       public boolean onLongClick(View v) { 
        try 
        { 
        if(db.delpin(name)) 
         Toast.makeText(getBaseContext(), "Delete successful", Toast.LENGTH_SHORT).show(); 
        else 
         Toast.makeText(getBaseContext(), "Delete failed", Toast.LENGTH_SHORT).show(); 

        Intent i = new Intent(); 
        i.setClassName("com.mdl.cyrestaurants.guide", "com.mdl.cyrestaurants.guide.pins"); 
        i.putExtra("type", getIntent().getStringExtra("type")); 
        startActivity(i); 
        finish(); 
        }catch(Exception e) 
        { 
        // --------------------------------- 
         // handle error code here 
         // You have problem with db.delpin(name) 
        // --------------------------------- 

         return false; 
        } 
        return false; 
       } 
      });
