我正在开发一个Android应用程序,我遇到了一个小问题
这是注册XML文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/ic_signup"
android:gravity="center_vertical"
android:orientation="vertical" >
<EditText
android:id="@+id/editTextEmail"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Email" />
<requestFocus />
<EditText
android:id="@+id/editTextFirstName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="First Name" />
<EditText
android:id="@+id/editTextLastName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Last Name" />
<EditText
android:id="@+id/editTextPassword"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Password"
android:inputType="textPassword" />
<EditText
android:id="@+id/editTextConfirmPassword"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Confirm Password"
android:inputType="textPassword" />
<EditText
android:id="@+id/editTextAge"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Age" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<TextView
android:id="@+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="@color/black" />
<EditText
android:id="@+id/editTextNumber"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Number" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/ic_signup"
android:gravity="center_vertical"
android:orientation="vertical" >
<Button
android:id="@+id/buttonCreateAccount"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="60dp"
android:background="@color/androidwhite"
android:text="Create Account" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
这是注册活动的onCreate()
方法
super.onCreate(savedInstanceState);
setContentView(R.layout.signup);
// Get instance of the database adapter
loginDataBaseAdapter = new LoginDataBaseAdapter(this);
loginDataBaseAdapter = loginDataBaseAdapter.open();
// Get references of views
mynumber = (TextView) findViewById(R.id.mynumber);
editTextEmail = (EditText) findViewById(R.id.editTextEmail);
editTextFirstName = (EditText) findViewById(R.id.editTextFirstName);
editTextLastName = (EditText) findViewById(R.id.editTextLastName);
editTextPassword = (EditText) findViewById(R.id.editTextPassword);
editTextConfirmPassword = (EditText) findViewById(R.id.editTextConfirmPassword);
editTextNumber = (EditText) findViewById(R.id.editTextNumber);
mynumber = (TextView) findViewById(R.id.mynumber);
editTextAge = (EditText) findViewById(R.id.editTextAge);
btnCreateAccount = (Button) findViewById(R.id.buttonCreateAccount);
btnCreateAccount.setOnClickListener(new View.OnClickListener() {
我不知道出了什么问题,但我无法看到&#34;创建帐户&#34;按钮了。可能是由于XML的变化。

这是因为您要将EditText
宽度设置为fill_parent
,这会占用设备的宽度并停止按钮显示。
更改:将EditText的宽度和高度更改为wrap_content
请尝试以下数据:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#123456"
android:gravity="center_vertical"
android:orientation="vertical" >
<EditText
android:id="@+id/editTextEmail"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Email" />
<requestFocus />
<EditText
android:id="@+id/editTextFirstName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="First Name" />
<EditText
android:id="@+id/editTextLastName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Last Name" />
<EditText
android:id="@+id/editTextPassword"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Password"
android:inputType="textPassword" />
<EditText
android:id="@+id/editTextConfirmPassword"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Confirm Password"
android:inputType="textPassword" />
<EditText
android:id="@+id/editTextAge"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Age" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<TextView
android:id="@+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="@android:color/white" />
<EditText
android:id="@+id/editTextNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Number" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/ic_launcher"
android:gravity="center_vertical"
android:orientation="vertical" >
<Button
android:id="@+id/buttonCreateAccount"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="60dp"
android:background="@android:color/white"
android:text="Create Account" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
希望它有效

尝试替换:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<TextView
android:id="@+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="@color/black" />
<EditText
android:id="@+id/editTextNumber"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Number" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/ic_signup"
android:gravity="center_vertical"
android:orientation="vertical" >
<Button
android:id="@+id/buttonCreateAccount"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="60dp"
android:background="@color/androidwhite"
android:text="Create Account" />
</LinearLayout>
</LinearLayout>
这样,如果你想让你的按钮在editTextNumber的右边:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal">
<TextView
android:id="@+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="@color/black" />
<EditText
android:id="@+id/EditTextNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Number" />
<Button
android:id="@+id/buttonCreateAccount"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@color/white"
android:text="Create Account" />
</LinearLayout>
或者如果你想在editText下使用你的按钮:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal">
<TextView
android:id="@+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="@color/black" />
<EditText
android:id="@+id/EditTextNumber"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Number" />
</LinearLayout>
<Button
android:id="@+id/buttonCreateAccount"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@color/white"
android:text="Create Account" />
