添加多个自定义视图以编程方式布局 [英] Add multiple custom views to layout programmatically

问题描述

如果我例如有空的布局是这样的：

If I for example have empty layout like this:

layout1.xml

layout1.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

</LinearLayout>

和其他一些布局是这样的：

And some other Layout like this:

layout2.xml

layout2.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView 1" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 2" />

    <Button
        android:id="@+id/button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 3" 
        android:layout_weight="1"/>

</LinearLayout>

我想 layout2.xml 添加到 layout1.xml 编程。我需要有多个不同的版本 layout2.xml 这时候我想我想补充。每个人都会对TextView的和按钮不同的文本。

I would like to add layout2.xml to layout1.xml programmatically. I would need to have multiple different version layout2.xml which I would add when I want. Each one would have different text on TextView and Buttons.

在定期Android设备上查看情况下，我通常会做类似这样与 addView ：

In case of regular Android View I would usually do it similarly like this with addView:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    TextView tv1 = new TextView(this);
    tv1.setText("HELLO");
    my_linear_layout.addView(tv1);

    Button btn2 = new Button(this);
    bt2.setText("WORLD");
    my_linear_layout.addView(btn2);
}

我该怎么办呢，如果我没有这样的TextView或按钮简单的东西，如果我有我自己的XML定义视图？

How can I do it if I don't have something simple like TextView or Button, and if I have my own xml defined View?

有没有可能以某种方式把里面适配器的所有意见像是一个ListView，然后在需要的时候得到它，只需要调用 addView 对这些意见？

Would it be possible to somehow put all the views inside adapter like for a ListView and then get it when needed and just call addView on those Views?

推荐答案

您可以充气layout2.xml文件，编辑文本，并把它添加到第一个布局：

You can inflate the layout2.xml file, edit the texts, and add it to the first layout :

public class MyActivity extends Activity {

    private ViewGroup mLinearLayout; 

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout1);
        mLinearLayout = (ViewGroup) findViewById(R.id.linear_layout);
        addLayout("This is text 1", "This is first button", "This is second Button");
    }

    private void addLayout(String textViewText, String buttonText1, String buttonText2) {
        View layout2 = LayoutInflater.from(this).inflate(R.layout.layout2, mLinearLayout, false);

        TextView textView = (TextView) layout2.findViewById(R.id.button1);
        Button button1 = (Button) layout2.findViewById(R.id.button2); 
        Button button2 = (Button) layout2.findViewById(R.id.button3);

        textView1.setText(textViewText);
        button1.setText(buttonText1);
        button2.setText(buttonText2);

        mLinearLayout.addView(layout2);
    }
}

您可能需要更改的android：在layout2.xml根视图 WRAP_CONTENT 的layout_height

You may want to change android:layout_height of the layout2.xml root view to wrap_content.
