从现场的EditText的Andr​​oid的getText [英] Android getText from EditText field

问题描述

我有来自外地的EditText让文本意图将其插入电子邮件作曲家的一个问题。我已经声明在布局文件的EditText场（@ + ID / vnosEmaila）：

I have a problem with getting text from EditText field to insert it in Email composer with intent. I've declared EditText field in layout file (@+id/vnosEmaila):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/navodiloEmail"
    android:text="@string/navodiloEmail"
    android:textSize="15dip"/>
<EditText 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/vnosEmaila"
    android:layout_below="@id/navodiloEmail"/>
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/navodiloZadeva"
    android:text="@string/navodiloZadeva"
    android:layout_below="@id/vnosEmaila"
    android:textSize="15dip"/>
<EditText 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/vnosZadeve"
    android:layout_below="@id/navodiloZadeva"/>
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/navodiloBody"
    android:text="@string/navodiloBody"
    android:layout_below="@id/vnosZadeve"
    android:textSize="15dip"/>
<EditText 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/vnosBody"
    android:layout_below="@id/navodiloBody"/>
<Button 
    android:id="@+id/klicIntentEmail"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/sestaviEmail"
    android:onClick="sestaviEmail"
    android:layout_below="@id/vnosBody"/>
</RelativeLayout>

按钮调用的onClick方法sestaviEmail我已经宣布它：

The button calls onClick method "sestaviEmail" and I have declared it:

public void sestaviEmail (View view){
    CharSequence test = getText(R.id.vnosEmaila);
    Toast toast = Toast.makeText(EmailGumb.this, test, Toast.LENGTH_LONG);
    toast.setGravity(Gravity.CENTER, 0, 0);
    toast.show();
    }

我只是显示它与面包，因为它的速度更快，但每次我尝试从现场的文字，我得到假。我发现所有其他问题了code这方法，而不是在布局声明按钮，也许这就是问题的一部分？

I'm just showing it with Toast because it's faster but everytime I try to get text from field I get "false". All other questions that I've found had code which declared Button in methods and not in layout, maybe this is a part of the problem?
