我想在上面显示一条带有文本的行,但它不应该是垂直或水平的,它应该是 45° 角。我正在使用包含 TextView 和 View 的 RelativeLayout (用于行)。在 RelativeLayout.LayoutParams 的帮助下,我尝试定义 RelativeLayout 的 x/y 位置。水平显示已经可以了,但是如何将其更改为 45° 角?
RelativeLayout branch_layout = (RelativeLayout) this
.findViewById(R.id.createrelativelayout);
LinearLayout branch_item = new LinearLayout(this);
branch_item.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
branch_item.setOrientation(1);
TextView tv = new TextView(this);
tv.setLayoutParams(new RelativeLayout.LayoutParams(pos, pos));
tv.setId(id);
tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
tv.setPadding(20, 0, 20, 0);
tv.setText(branch_name);
tv.setOnClickListener(this);
Rect bounds = new Rect();
Paint textPaint = tv.getPaint();
textPaint.getTextBounds(branch_name, 0, branch_name.length(), bounds);
View underline = new View(this);
underline.setLayoutParams(new LayoutParams(bounds.width() + 40, 1));
underline.setBackgroundColor(Color.parseColor("#000000"));
branch_item_layout = new RelativeLayout(this);
branch_item_layout.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
Display display = getWindowManager().getDefaultDisplay();
//x
params.leftMargin = display.getWidth()/2;
//y
params.topMargin = ((display.getHeight()/2)-(((LinearLayout) this
.findViewById(R.id.createlinearlayout3)).getWidth()/2)-48);
//end x
params.bottomMargin = params.leftMargin + bounds.width();
//end y
params.rightMargin = (int) (params.leftMargin - (bounds.width()*Math.sin(45)));
branch_item.addView(tv);
branch_item.addView(underline);
branch_item_layout.addView(branch_item, params);
branch_layout.addView(branch_item_layout);
全屏实现只针对“横向” x 0-800, y 0-440 现在
first x = 400
first y = 114
end x = 434
end y = 371
计划以 45° 角一起显示字符串和线条。线的长度以字符串宽度为方向。
希望任何人都可以帮助我解决这个难题,
