这是我的Home.xml布局文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rellay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/placesgradient">
<Button
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="click"
/>
**<I want to include another layout here on a click of a button dynamically on click of a button >**
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_below="@id/btn2"
android:text="hello this is text..see above" />
</RelativeLayout>
这是我的Home.java文件
public class Home extends Fragment implements OnClickListener {
Button b1;
RelativeLayout r1;
View rootView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.home, container, false);
b1 = (Button) rootView.findViewById(R.id.btn2);
b1.setOnClickListener(this);
return rootView;
}
@Override
public void onClick(View arg0) {
ViewGroup con = null;
r1 = (RelativeLayout) rootView.findViewById(R.id.rellay);
LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
r1.addView(layoutInflater.inflate(R.layout.test1, con , false));
}
}
当我单击按钮时,它将test1.xml布局文件放在home.xml布局的顶部。我需要它在按钮和文本之间。我之前在堆栈上检查了这段代码,但它似乎与FragmentActivity无关。这里1表示该情况下的索引或第二个孩子。
rl.addView(1, layoutInflater.inflate(R.layout.content_layout, this, false) );
我怎样才能实现它?帮助!

我会在您想要布局的位置放置一些容器视图:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rellay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/placesgradient">
<Button
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="click"
/>
<FrameLayout
android:id="@+id/flContainer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_below="@id/btn2"
android:text="hello this is text..see above" />
</RelativeLayout>
然后你可以像这样检索片段中的容器:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.home, container, false);
// Retrieve your container
flContainer = rootView.findViewById(R.id.flContainer);
b1 = (Button) rootView.findViewById(R.id.btn2);
b1.setOnClickListener(this);
return rootView;
}
稍后当您想要添加布局时,可以将子项添加到FrameLayout
,如下所示:
flContainer.addView(subLayout);
如果您以后想要更改容器中的布局,可以这样做:
flContainer.removeAllViews();
flContainer.addView(otherLayout);

使用LayoutParams。
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.BELOW, R.id.btn2);
r1.addView(layoutInflater.inflate(R.layout.test1, con , false),params);
或者将视图放在您的布局中,并使用View.setVisibility(View.GONE/View.VISIBLE)
