如果有文本，请从文本字段中获取文本

Question

这是我的代码：

if (e0.getText().length()==0)   
   email.putExtra(Intent.EXTRA_TEXT, e01+n02+n03+n05);
if (e1.getText().length()==0)   
   email.putExtra(Intent.EXTRA_TEXT, e00+n02+n03+n05);
if (n2.getText().length()==0)   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01+n03+n05);
if (n3.getText().length()==0)   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01+n02+n05);
if (n5.getText().length()==0)   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01+n02+n03);
if (e0.getText().length()==0 && e1.getText().length()==0)       
   email.putExtra(Intent.EXTRA_TEXT, n02+n03+n05);
if (e0.getText().length()==0 && n2.getText().length()==0 )                                                                                                
   email.putExtra(Intent.EXTRA_TEXT, e01+n03+n05);
if (e0.getText().length()==0 && n3.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e01+n02+n05);
if (e0.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e01+n02+n03);
if (e1.getText().length()==0 && n2.getText().length()==0 )    
   email.putExtra(Intent.EXTRA_TEXT, e00+n03+n05);
if (e1.getText().length()==0 && n3.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+n02+n05);
if (e1.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+n02+n03);
if (n2.getText().length()==0 && n3.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01+n05);
if (n2.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01+n03);
if (n3.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01+n02);
if (e0.getText().length()==0 && e1.getText().length()==0 && n2.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, n03+n05);
if (e0.getText().length()==0 && e1.getText().length()==0 && n3.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, n02+n05);
if (e0.getText().length()==0 && e1.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, n02+n03);
if (e0.getText().length()==0 && n2.getText().length()==0 && n3.getText().length()==0 )    
   email.putExtra(Intent.EXTRA_TEXT, e01+n05);
if (e0.getText().length()==0 && n2.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e01+n03);
if (e0.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e01+n02);
if (e1.getText().length()==0 && n2.getText().length()==0 && n3.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+n05);
if (e1.getText().length()==0 && n2.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+n03);
if (e1.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+n02);
if (n2.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0 )   
   email.putExtra(Intent.EXTRA_TEXT, e00+e01);         
if (e0.getText().length()==0 && e1.getText().length()==0 && n2.getText().length()==0 && n3.getText().length()==0 )   
    email.putExtra(Intent.EXTRA_TEXT,n05);
if (e0.getText().length()==0 && e1.getText().length()==0 && n2.getText().length()==0 && n5.getText().length()==0 )   
    email.putExtra(Intent.EXTRA_TEXT,n03);
if (e0.getText().length()==0 && e1.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0 )   
    email.putExtra(Intent.EXTRA_TEXT,n02);         
if (e0.getText().length()==0 && n2.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0 )   
    email.putExtra(Intent.EXTRA_TEXT,e01);
if (e1.getText().length()==0 && n2.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0 )   
    email.putExtra(Intent.EXTRA_TEXT,e00);
if (e0.getText().length()==0 && e1.getText().length()==0 && n2.getText().length()==0 && n3.getText().length()==0 && n5.getText().length()==0){
    Toast.makeText(this, "Wprowadź wartości zamówienia",Toast.LENGTH_SHORT).show();
       return;  
};

现在： 我有5个文本字段（数字），这些是我在我的应用程序中订购的一些部分。我把它们放到email.putExtra（Intent.EXTRA_TEXT，e01）。 我怎么能把我的EXTRA_TEXT看起来正确的字符串放在例如： “电极E0 - ”e00“pcs”
