LayoutInflater liInflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
linear.addView(liInflater
.inflate(R.layout.main_alllatestnewslist, null));
lv = (ListView) findViewById(android.R.id.list);
for (int i = 0; i < webservice.news.size(); i++) {
maintitle = (TextView) findViewById(R.id.text_particularlatestnewstitle);
LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams)maintitle.getLayoutParams();
layoutParams.setMargins(50, 0, 0, 0); <-- method one
maintitle.setPadding(50, 0, 0, 0); <-- method two
maintitle.setLayoutParams(layoutParams);
int margin = 100; <-- method three
((MarginLayoutParams) maintitle.getLayoutParams()).leftMargin = margin;
}
SimpleAdapter adapter = new SimpleAdapter(this, fillMaps,
R.layout.main_alllatestnewslist, from, to);
lv.setAdapter(adapter);
As you can see i had used THREEmethods to set margin/ padding of textview in a listview but not success.
如您所见，我使用了三种方法在列表视图中设置文本视图的边距/填充，但没有成功。
I am using xml textview instead of create new.
我正在使用 xml textview 而不是创建新的。
I want to manually set because i got if / elsestatement there as did not post out.
我想手动设置，因为我在那里得到了if / else语句，因为没有发布。
I am totally out of idea how to set it in java.
我完全不知道如何在java中设置它。
Please provide me a idea that workable one, thanks
请给我一个可行的想法，谢谢
((MarginLayoutParams) maintitle.getLayoutParams()).leftMargin = margin;

maintitle.setPadding(50, 0, 0, 0);(method 2) should work.
maintitle.setPadding(50, 0, 0, 0);（方法2）应该有效。
I think the problem is that, although you do a lot of changes to the TextView, at the end you kind of inflate a new layout again in:
我认为问题在于，尽管您对 进行了大量更改TextView，但最终您还是在以下内容中再次膨胀了一个新布局：
SimpleAdapter adapter = new SimpleAdapter(this, fillMaps,
R.layout.main_alllatestnewslist, from, to);
so, make a custom adapter, then inflate and customize your TextViewin the getView().
因此，制作一个自定义适配器，然后TextView在getView().

Be careful, (int) pixels != dp
小心，（int）像素！= dp
public int dp2px(int dp) {
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, context.getResources().getDisplayMetrics());
}

Try the following code, it works for me.
试试下面的代码，它对我有用。
textView.setX(40);
textView.setX(40);
My solution is for SDK 14 and above. Not in ListView but RecyclerView.
我的解决方案适用于 SDK 14 及更高版本。不在 ListView 中，而是在 RecyclerView 中。
