我如何以编程方式添加余量的TextView甚至为的TableRow基于android应用程序? [英] how do i add margin programmatically for TextView or even TableRow for android-based app?
问题描述
您好,我已经试过增加保证金编程
我已经尝试使用
TextView的电视=新的TextView(本);
的LayoutParams PARAMS =新的LayoutParams(WRAP_CONTENT,WRAP_CONTENT);
params.setMargins(100,20,0,0);
layout.addView(TV,则params);
它使用android.widget.LinearLayout.LayoutParams,但因为表,我得到了运行时错误吧。
我应该怎么做呢?
这是我的code:
//创建表行
TRA的TableRow =新的TableRow(本);
trA.setId(1000 + I);
trA.setLayoutParams(新的LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); //将数据添加到表行
TextView的TVA =新的TextView(本);
tvA.setId(2000 + I);
tvA.setText(aList.get(ⅰ)的ToString());
tvA.setTextSize(18);
tvA.setTextColor(Color.BLACK);
tvA.setClickable(真);
tvA.setOnClickListener(本);
tvA.setSingleLine(假);
tvA.setHorizontallyScrolling(假);
tvA.setWidth(0);
tvA.setHeight(100); trA.addView(TVA);
tableA.addView(TRA,新TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
==与进口android.widget.TableLayout.LayoutParams编辑; ==
我添加了这个在那里我宣布tablerow的结束
的LayoutParams PARAMS =新的LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
params.setMargins(0,0,0,20);
和编辑的addView在表A
tableA.addView(TVA,则params);
我在日志猫错误,显示相当了很多,所以我给了主要的一个位置:指定的小孩已经有一个父。您必须先对孩子的父母打电话removeView()。
TableRow.LayoutParams PARAMS =新TableRow.LayoutParams(WRAP_CONTENT,WRAP_CONTENT);
params.setMargins(100,20,0,0);
hi i've tried to add margin programmatically
i've tried using
TextView tv = new TextView(this);
LayoutParams params = new LayoutParams(WRAP_CONTENT, WRAP_CONTENT);
params.setMargins(100, 20, 0, 0);
layout.addView(tv, params);
which uses android.widget.LinearLayout.LayoutParams, but because of the table, i got runtime error for it.
how should i do it then ?
this is my code :
//create table row
TableRow trA = new TableRow(this);
trA.setId(1000+i);
trA.setLayoutParams(new LayoutParams (LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
//add data to table row
TextView tvA = new TextView (this);
tvA.setId(2000+i);
tvA.setText(aList.get(i).toString());
tvA.setTextSize(18);
tvA.setTextColor(Color.BLACK);
tvA.setClickable(true);
tvA.setOnClickListener(this);
tvA.setSingleLine(false);
tvA.setHorizontallyScrolling(false);
tvA.setWidth(0);
tvA.setHeight(100);
trA.addView(tvA);
tableA.addView(trA,new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
== edited with import android.widget.TableLayout.LayoutParams; ==
i added this at the end where i declare the tablerow
LayoutParams params = new LayoutParams (LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
params.setMargins(0, 0, 0, 20);
and edited the addView at tableA
tableA.addView(tvA, params);
i have error in the log cat, it display quite alot, so i gave the main one here : The specified child already has a parent. You must call removeView() on the child's parent first.
TableRow.LayoutParams params = new TableRow.LayoutParams(WRAP_CONTENT, WRAP_CONTENT);
params.setMargins(100, 20, 0, 0);
