Question

例如。

空是第一个EditText，total_empty是另一个编辑文本如果我在空的edittext中输入1意味着它必须同时在total_empty edittext上显示为1。

之后我有一个名为new.i的EditText将在EditText new中给出3作为值。

之后我必须添加上面三个EditText值（1 + 2 + 3）并在另一个名为fill的EditText中显示总和。

Atlast我还有另一个名为total_fill的editText，我必须在上面的“fill”edittext中显示相同的值。

我的代码在下面给出

的EditText

empty_cyl_recvd,new_cyl_recvd,filled_cyl_unload,dmg_cyl_recvd,total_filled_cyl,total_dmg_cyl,total_em
pty_cyl;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    empty_cyl_recvd = (EditText) findViewById(R.id.empty_cyl_recvd);
    empty_cyl_recvd.setInputType(InputType.TYPE_CLASS_NUMBER);
    empty_cyl_recvd.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

 new_cyl_recvd = (EditText) findViewById(R.id.new_cyl_recvd);
 new_cyl_recvd.setInputType(InputType.TYPE_CLASS_NUMBER);
       new_cyl_recvd.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

 filled_cyl_unload = (EditText) findViewById(R.id.filled_cyl_unload);
 filled_cyl_unload.setInputType(InputType.TYPE_CLASS_NUMBER);
 filled_cyl_unload.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

 dmg_cyl_recvd = (EditText) findViewById(R.id.dmg_cyl_recvd);
 dmg_cyl_recvd.setInputType(InputType.TYPE_CLASS_NUMBER); 
 dmg_cyl_recvd.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

     total_dmg_cyl=(EditText)findViewById(R.id.sdff);
 total_empty_cyl=(EditText)findViewById(R.id.wertyu);
