問題描述

我在從 EditText 字段獲取文本以將其插入到電子郵件編輯器中時(shí)遇到問題.我已經(jīng)在布局文件 (@+id/vnosEmaila) 中聲明了 EditText 字段:

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>

按鈕調(diào)用 onClick 方法sestaviEmail"，我已經(jīng)聲明了它:

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();
    }

我只是用 Toast 展示它，因?yàn)樗欤看挝覈L試從字段中獲取文本時(shí)，我都會(huì)得到假".我發(fā)現(xiàn)的所有其他問題的代碼都在方法中而不是在布局中聲明了 Button，也許這是問題的一部分?

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?

如何從 EditText 獲取文本的示例代碼.

Sample code for How to get text from EditText.

Android Java 語法

val value = text.text.toString()
