我目前正在一个项目中，当用户单击电子邮件按钮时，它将带他到一个对话框，其中他的电子邮件已插入编辑文本中，但是我面临的问题是{{1} }函数未实现。 这是我的代码：
setText我已经测试过，看看是否正在解析该变量，即使在尝试Button Emailbtn = (Button) dialog.findViewById(R.id.btnEmail);
Emailbtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
v.setSelected(true);
final Dialog dialog = new Dialog(ViewQuotesD.this);
dialog.getWindow();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialemail);
//Getting content for email
final Button btnsend = (Button) dialog.findViewById(R.id.btnEmail);
btnsend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final EditText emaill = (EditText) dialog.findViewById(R.id.edtEmail);
emaill.setText(SlectedName);
String email = emaill.getText().toString().trim();
String subject = "Your Quotations";
String message = "Hi " + SelectedEmail +" "+SelectedSurname+"\n"+
"FABRIC: \n"+
"Total price of fabric = R" + SelectedFabricTotal+
"\n"+
"LINING: \n"+
"Total price of lining = R" + SelectedLiningtotal+
"\n"+
"LABOUR: \n"+
"Total labour cost on fabric = R" + SelectedFabricLabour+
"\n"+
"VOIL: \n"+
"Total price of voil = R" + SelectedVoilTotal +"\n"+
"Labour price on voil = R" + SelectedVoilLabour+
"\n"+
"RAILINGS: \n"+
"Total price of railings = R" + SelectedRailTotal+
"\n"+
"VALANCE: \n"+
"Total price of valance = R" + SelectedValTotal+
"\n"+
"INSTALLATION: \n"+
"Total installation cost = R" + SelectedInstall+
"\n"+
"GRAND TOTAL = R" + SelectedPrice;
//Creating SendMail object
SendMail sm = new SendMail(ViewQuotesD.this, email, subject, message);
//Executing sendmail to send email
sm.execute();
finish();
startActivity(getIntent());
Toast.makeText(ViewQuotesD.this , "Email sent" , Toast.LENGTH_LONG).show();
}
});
}
});
dialog.show();
这样的普通字符串的情况下，它也并未在SetText上实现显示。
答案 0 :(得分：0)
如果代码的逻辑正确，请检查布局xml文件，也许EditText的内容已更改，但由于文本颜色与背景颜色相同而无法显示。
尝试更改Edittext的颜色进行测试。
