Android:合并xml并以编程方式生成布局

Question

我有需求，我需要结合以编程方式生成的布局和xml。我应该采取什么方法?请让我知道。谢谢你。

生成布局:

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    LinearLayout audio = new LinearLayout(this);
    audio.setGravity(Gravity.BOTTOM | Gravity.CENTER);
    RecordButton = new RecordButton(this);
    audio.addView(RecordButton,
                new LinearLayout.LayoutParams(
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    Gravity.CENTER | Gravity.BOTTOM));
    PlayButton = new PlayButton(this);
    audio.addView(PlayButton,
                new LinearLayout.LayoutParams(
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    Gravity.CENTER | Gravity.BOTTOM));
    setContentView(audio);
}

xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
android:gravity="top">
<Button
android:id="@+id/next"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="130dp"
android:background="#54C571"
android:text="Next"
android:textColor="#FFFFFF"
android:textSize="23sp"
android:textStyle="bold" />

创建一个容器视图来存放视图，并将生成的视图添加到其中，

这是xml，

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFFFFF"
    android:gravity="top">
    <Button
        android:id="@+id/next"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="130dp"
        android:background="#54C571"
        android:text="Next"
        android:textColor="#FFFFFF"
        android:textSize="23sp"
        android:textStyle="bold" />
    <!-- create a container view to hold your view -->
    <LinearLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/next" />
</RelativeLayout>

在你的代码中，

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.the_above_layout);
    LinearLayout container = (LinearLayout) findViewById(R.id.container);

    LinearLayout audio = new LinearLayout(this);
    audio.setGravity(Gravity.BOTTOM | Gravity.CENTER);
    RecordButton = new RecordButton(this);
    audio.addView(RecordButton,
                new LinearLayout.LayoutParams(
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    Gravity.CENTER | Gravity.BOTTOM));
    PlayButton = new PlayButton(this);
    audio.addView(PlayButton,
                new LinearLayout.LayoutParams(
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    Gravity.CENTER | Gravity.BOTTOM));

    // add the view to your container
    container.addView(audio);
}
