以編程方式從textviews設置頁邊距

Question

我試圖製作一個視圖，其中有編程的文本視圖之間存在靜態頁邊距，我如何使這發生？我想了很多，我

setMargins(viewEvent, 20, placeSum, 0, 0); 

只是設置頁邊距頂部的佈局和說，我想使利潤率以上的TextView。

這裏是我的循環

int set=0; 
     for (int i = 0; i < partEvents.length; i++) { 
      RelativeLayout relativeLayout = (RelativeLayout) eventView.findViewById(R.id.eventRelativeLayout); 
      TextView viewEvent = new TextView(getActivity()); 
      viewEvent.setBackgroundResource(R.drawable.eventbg); 

      viewEvent.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, 
        RelativeLayout.LayoutParams.WRAP_CONTENT)); 



      String startHour = getHourFromString(partEvents[i][2]); 
      String startMinute = getMinuteFromString(partEvents[i][2]); 
      String endHour = getHourFromString(partEvents[i][3]); 
      String endMinute = getMinuteFromString(partEvents[i][3]); 

      viewEvent.setText(partEvents[i][0]+ "\n" + 
      partEvents[i][1] + "\n" 
      + startHour + ":" + startMinute + "-" + endHour + ":" + endMinute ); 


      final float scale = getResources().getDisplayMetrics().density; 
      int placeSum = (int) (10 + set * scale + 0.5f); 
      setMargins(viewEvent, 20, placeSum, 0, 0); 


      viewEvent.setTextSize(20); 



      set=set+100; 
      try { 
       relativeLayout.addView(viewEvent); 

      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     }

Answer 1

保證金在LayoutParams（例如，RelativeLayout.LayoutParams你的情況）作爲

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT); 
params.setMargins(left, top, right, bottom); 
viewEvent.setLayoutParams(params); 

設置

更新

如果您需要添加TextViewš垂直然後使用LinearLayout作爲

<!-- inside scrollview --> 
<LinearLayout 
    android:id="@+id/eventLinearLayout" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" /> 

，並以編程爲

LinearLayout linearLayout = (LinearLayout) eventView.findViewById(R.id.eventLinearLayout); 

for (int i = 0; i < partEvents.length; i++) { 

    TextView viewEvent = new TextView(getActivity()); 

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
    params.setMargins(left, top, right, bottom); 
    viewEvent.setLayoutParams(params); 

    // rest of your code 

    linearLayout.addView(viewEvent); 
} 

使用LinearLayout，會自動處理您的TextView擴張和收縮。
