Question

这是我到目前为止所做的：

LinearLayout category_layout = new LinearLayout(getActivity());
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams (LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(15, 5, 5, 10);
category_layout.setLayoutParams(params);
//Add Category Title
TextView category_title = new TextView(getActivity());
category_title.setText("MEN " + i);
category_title.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
category_title.setPadding(10,0,0,0); category_title.setTextColor(getResources().getColor(R.color.text_color));
category_title.setTypeface(null, Typeface.BOLD);
category_layout.addView(category_title);
TextView category_more = new TextView(getActivity());
category_more.setText("MORE");
LinearLayout.LayoutParams lp_ineer_ver = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
lp_ineer_ver.gravity = Gravity.RIGHT;
category_more.setLayoutParams(lp_ineer_ver);
category_more.setPadding(0,0,10,0);
category_more.setTextColor(getResources().getColor(R.color.text_color));
category_more.setTypeface(null, Typeface.BOLD);
category_more.setGravity(Gravity.RIGHT);
category_layout.addView(category_more);

现在TextView＆＃34;更多＆＃34;不要出现，但如果我试着评论该行

category_layout.addView(category_title);

然后它显示并完美对齐。发生了什么？不管怎样，请帮忙!!!

Answer 1

试试这个：

您需要在第一个textview中将宽度设置为换行内容。

category_title.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CON‌TENT,
LinearLayout.LayoutParams.WRAP_CONTENT));

示例代码

LinearLayout category_layout = new LinearLayout(getActivity());
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams
(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(15, 5, 5, 10);
category_layout.setLayoutParams(params);

 //Add Category Title
 TextView category_title = new TextView(getActivity());
 category_title.setText("MEN " + i);
 category_title.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CON‌TENT, LinearLayout.LayoutParams.WRAP_CONTENT));
 category_title.setPadding(10,0,0,0);
 category_title.setTextColor(getResources().getColor(R.color.text_color));
 category_title.setTypeface(null, Typeface.BOLD);          
 category_layout.addView(category_title);


 TextView category_more = new TextView(getActivity());
 category_more.setText("MORE");
 LinearLayout.LayoutParams lp_ineer_ver = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
 lp_ineer_ver.gravity = Gravity.RIGHT;
 category_more.setLayoutParams(lp_ineer_ver);
 category_more.setPadding(0,0,10,0);
 category_more.setTextColor(getResources().getColor(R.color.text_color));
 category_more.setTypeface(null, Typeface.BOLD);
 category_more.setGravity(Gravity.RIGHT);

 category_layout.addView(category_more);

Answer 2

指定weightsum和weights将空间划分为相等的一半

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams
                                (LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
                        category_layout.setWeightSum(2);
                        params.setMargins(15, 5, 5, 10);
                        category_layout.setLayoutParams(params);

    LinearLayout.LayoutParams titleParams = (LinearLayout.LayoutParams) category_layout.getLayoutParams();
    titleParams.weight = 1;
    category_title.setGravity(Gravity.START);
    category_title.setLayoutParams(titleParams);

    LinearLayout.LayoutParams moreParams = (LinearLayout.LayoutParams) category_layout.getLayoutParams();
    moreParams.weight = 1;
    category_more.setGravity(Gravity.END);
    category_more.setLayoutParams(moreParams);

将2 TextView添加到LinearLayout中（一个左对齐，一个右对齐）
