我想在相对布局中膨胀相对布局。但它只是在膨胀一次之后才膨胀，请帮我看看我的代码有什么问题。

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建议和帮助之后我做了什么

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);
    }

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，其中子级的位置相对于彼此或父级进行描述。如果要使用相对布局，则必须使用addrule属性，否则所有子级将被绘制在前一个子级之上.

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);
    }

并为活动放这个

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    LinearLayout main = (LinearLayout) findViewById(R.id.main_passenger_details_layout);

    for (int i = 0; i < 9; i++) {
        LayoutInflater inflater = (LayoutInflater) getApplicationContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View row = inflater.inflate(R.layout.activity_second, main, false);
        main.addView(row);
    }
}

LayoutInflater 正在工作，并且正在添加九次布局。但是您看不到所有视图，因为所有布局都添加到另一个 RelativeLayout，因此它们将一个添加到另一个。

因此，为了克服在父视图中使用具有垂直方向而不是 Relativelayout 的 LinearLayout

每次您将视图添加到该相对布局时，它都会添加到相同的位置..就像视图堆栈一样..你看不到下面的视图..最好尝试LinearLayout .. 视图将水平或垂直添加..so你可以看到那九个视图..

// Replace this line
 View view = getLayoutInflater().inflate(R.layout.passenger_details_layout, main,false);
                                             to
