Question

我试图查看我以编程方式创建的textviews之间存在静态边距的视图，我该如何才能实现这一点？我尝试了很多和我的

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

只是在布局中设置页边距，并且如上所述我想为上面的textview设置页边距。

这是我的循环

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();
            }
        }

保证金设置在LayoutParams（例如，您的RelativeLayout.LayoutParams}中

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

<强>更新

如果您需要垂直添加TextView，请使用LinearLayout作为

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

以编程方式

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，会自动处理您的TextView扩展和缩小。
