的setContentView和布局（机器人） [英] setContentView and layout (android)

问题描述

我有一个活动的布局，但我也希望显示一些文本。
我不能使用的标签，因为我没有这两个布局。是否有任何等效，可以使布局和的setContentView（TextView的）语句一起工作？

我的code是：

 公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    意向意图= getIntent（）;
    字符串消息= intent.getStringExtra（FirstActivity.EXTRA_MESSAGE）;    TextView的文本=新的TextView（本）;
    text.setText（消息）;
    的setContentView（R.layout.second）;
}
 

我试过

  RelativeLayout的RelativeLayout的=新的RelativeLayout（本）;
RelativeLayout.LayoutParams lParams =新RelativeLayout.LayoutParams（
    RelativeLayout.LayoutParams.FILL_PARENT，
    RelativeLayout.LayoutParams.FILL_PARENT）;
 

然后

  relativeLayout.addView（文本）;
 

但我得到这个错误：

  

字段 ViewGroup.LayoutParams.FILL_PARENT 是pcated德$ P $

解决方案

您与方法有点糊涂的setContentView（）。您可以设置从活动的布局键，进入这个布局您可以添加 TextViews 只要你想或许多需要。

或者你也可以设置programmaticaly布局和添加也添加小部件在这种方式。

  RelativeLayout的RelativeLayout的=新的RelativeLayout（本）;RelativeLayout.LayoutParams lParams =新RelativeLayout.LayoutParams（
                RelativeLayout.LayoutParams.FILL_PARENT，
                RelativeLayout.LayoutParams.FILL_PARENT）;//创建部件
        TextView的文本=新的TextView（本）;
        text.setText（简单的虚拟文本）;        //最后你的TextView添加到RelativeLayout的
        relativeLayout.addView（文本）;        //并设置您的布局像主要内容
        的setContentView（RelativeLayout的，lParams）;
 

您也可以为小部件对准设置的规则。

I have a layout for an activity but I also want to display some text. I can't use the tag because I don't have two layouts. Is there any equivalent that can make a layout and a setContentView(textView) statement work together?

my code is:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    String message = intent.getStringExtra(FirstActivity.EXTRA_MESSAGE);

    TextView text = new TextView(this);
    text.setText(message);


    setContentView(R.layout.second);
}

I tried

RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams lParams = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.FILL_PARENT,
    RelativeLayout.LayoutParams.FILL_PARENT);

and then

relativeLayout.addView(text);

but I got this error:

The field ViewGroup.LayoutParams.FILL_PARENT is deprecated

解决方案

You are little confused with method setContentView(). You could set layout from your Activity and into this Layout you can add TextViews as many as you want or need.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#3B3B3B"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="10dp">

        <TextView 
            android:id="@+id/title"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/title"
            android:textSize="26dp"
            android:layout_marginTop="10dp"
            android:textStyle="bold"
            />

        <TextView 
            android:id="@+id/email"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/email"
            android:layout_marginTop="15dp"
            android:layout_marginBottom="5dp"
            />

        <EditText
            android:id="@+id/emailForm"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:inputType="textEmailAddress"
            android:background="@drawable/myshape"
            />

        <TextView 
            android:id="@+id/password"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/password"
            android:layout_marginTop="10dp"
            android:layout_marginBottom="5dp"
            />

        <EditText 
            android:id="@+id/passwordForm"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:inputType="textPassword"
            android:background="@drawable/myshape"
            />

        <Button 
            android:id="@+id/loginBtn"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/loginBtn"
            android:layout_marginTop="40dp"
            />

        <TextView 
            android:id="@+id/registerLink"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:textStyle="bold"
            android:text="@string/register"
            android:textColor="#00BADB"
            android:layout_marginTop="20dp"
            />

        <TextView 
            android:id="@+id/registerLink"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:textStyle="bold"
            android:text="@string/register"
            android:textColor="#00BADB"
            android:layout_marginTop="20dp"
            />

        <TextView 
            android:id="@+id/registerLink"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:textStyle="bold"
            android:text="@string/register"
            android:textColor="#00BADB"
            android:layout_marginTop="20dp"
            />
    </LinearLayout>

Or you can set layout programmaticaly and add also add widgets in this approach.

RelativeLayout relativeLayout = new RelativeLayout(this);

RelativeLayout.LayoutParams lParams = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT,
                RelativeLayout.LayoutParams.FILL_PARENT);

//create widgets
        TextView text = new TextView(this);
        text.setText("Simply dummy text");

        // finally add your TextView to the RelativeLayout
        relativeLayout.addView(text);

        // and set your layout like main content
        setContentView(relativeLayout, lParams);

You can also set rules for aligning of widgets.
