提升相对布局Android
作者：互联网
我想在相对布局中膨胀相对布局.但是它只是膨胀一次之后它没有膨胀请帮我解决我的代码中的问题.
活动代码
LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout main = (RelativeLayout)findViewById(R.id.passenger_details_layout);
for(int i=0;i<9;i++){
View view = getLayoutInflater().inflate(R.layout.passenger_details_layout, main,false);
main.addView(view);
}
在@Ritaban建议并帮助我做了我所做的
活动代码：
LayoutInflater inflater;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_itineary_page);
inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
/*
* LayoutInflater inflater = (LayoutInflater) getBaseContext()
* .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
*/
LinearLayout main = (LinearLayout) findViewById(R.id.main_passenger_details_layout);
for (int i = 0; i < 2; i++) {
inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout layout = (RelativeLayout) inflater.inflate(
R.layout.passenger_details_layout, main, false);
main.addView(layout, i);
}
RelativeLayout lay = (RelativeLayout) findViewById(R.id.thingstoshowbelow);
RelativeLayout.LayoutParams params = (android.widget.RelativeLayout.LayoutParams) lay
.getLayoutParams();
params.addRule(RelativeLayout.BELOW, R.id.main_passenger_details_layout);
lay.setLayoutParams(params);
lay.setVisibility(View.VISIBLE);
}

解决方法:
使用线性布局作为父视图并给出android：orientation =“vertical”.相对布局是一种布局,其中子项的位置相对于彼此或父项描述.如果要使用相对布局,则必须使用addrule属性,否则将覆盖前一个子项的所有子项.
例如：
<Linearlayout
android:id="@+id/passenger_details_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/travel_itin_header"
android:layout_marginTop="2dp"
android:gravity="center_vertical"
android:orientation = "vertical" >
</Linearlayout>
在活动中：
LayoutInflater inflater = (LayoutInflater)getBaseContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout main =(LinearLayout)findViewById(R.id.passenger_details_layout);
for(int i=0;i<9;i++){
View view = inflater.inflate(R.layout.passenger_details_layout, null);
main.addView(view);
}
