如何使短代码

Question

这是我的第一个应用程序的代码的一部分。目前，我只添加了2个默认值gab的TextView，点击它们弹出6个值PopupMenu。通过单击PopupMenu中的任何值，TextView的值将更改为单击的值（不会更改其他未单击的TextView值）。我打算添加像100或甚至更多这种TextViews。每个人写作，复制和编辑ID等都太乱了。

这是如何缩短的？ 值的数量不会改变（6），ViewId的数量（例如augli_mervieniba和bites_mervieniba）将是巨大的。

public void popup_mervieniba(final View view) 
    { 
     PopupMenu popupMenu = new PopupMenu(this, view); 
     MenuInflater menuInflater = popupMenu.getMenuInflater(); 
     popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { 
      @Override 
      public boolean onMenuItemClick(MenuItem item) { 

这部分是，如果第一TextView的被点击

   if (view==findViewById(R.id.augli_mervieniba)) 

        switch (item.getItemId()) { 
         case R.id.gab: 
          TextView t_gab = (TextView) findViewById(R.id.augli_mervieniba); 
          t_gab.setText(R.string.gab); 
          return true; 
         case R.id.iep: 
          TextView t_iep = (TextView) findViewById(R.id.augli_mervieniba); 
          t_iep.setText(R.string.iep); 
          return true; 
         case R.id.g: 
          TextView t_g = (TextView) findViewById(R.id.augli_mervieniba); 
          t_g.setText(R.string.g); 
          return true; 
         case R.id.kg: 
          TextView t_kg = (TextView) findViewById(R.id.augli_mervieniba); 
          t_kg.setText(R.string.kg); 
          return true; 
         case R.id.ml: 
          TextView t_ml = (TextView) findViewById(R.id.augli_mervieniba); 
          t_ml.setText(R.string.ml); 
          return true; 
         case R.id.l: 
          TextView t_l = (TextView) findViewById(R.id.augli_mervieniba); 
          t_l.setText(R.string.l); 
          return true; 
       } 

如果第二TextView的被点击的代码

return false; 
      } 
     }); 
     menuInflater.inflate(R.menu.popup_mervieniba, popupMenu.getMenu()); 
     popupMenu.show(); 
    } 

Answer 1

  else if (view==findViewById(R.id.bietes_mervieniba)) 
        switch (item.getItemId()) { 
         case R.id.gab: 
          TextView t_gab = (TextView) findViewById(R.id.bietes_mervieniba); 
          t_gab.setText(R.string.gab); 
          return true; 
         case R.id.iep: 
          TextView t_iep = (TextView) findViewById(R.id.bietes_mervieniba); 
          t_iep.setText(R.string.iep); 
          return true; 
         case R.id.g: 
          TextView t_g = (TextView) findViewById(R.id.bietes_mervieniba); 
          t_g.setText(R.string.g); 
          return true; 
         case R.id.kg: 
          TextView t_kg = (TextView) findViewById(R.id.bietes_mervieniba); 
          t_kg.setText(R.string.kg); 
          return true; 
         case R.id.ml: 
          TextView t_ml = (TextView) findViewById(R.id.bietes_mervieniba); 
          t_ml.setText(R.string.ml); 
          return true; 
         case R.id.l: 
          TextView t_l = (TextView) findViewById(R.id.bietes_mervieniba); 
          t_l.setText(R.string.l); 
          return true; 
       } 

端这部分是针对

这样做;

ActivityClass 
{ private TextView tv1, tv2....... 
onCreate() 
{ 
tv1 = (TextView) findViewById(); 
tv2 = (TextView) findViewById(); 
} 

switch() 
{ 
case R.id.gap: 
tv1.setText(); 
return; 
……………… 
}
