问题 I'm trying to figure out the difference between the layout params for relative layout, specifically alignParentRight and alignParentEnd (also alignParentLeft and alignParentStart). Reading the reference doesn't help much, I figured the end of a parent was always its right. Is there any difference to this? Is one depreciated now? 回答1: I figured the end of a parent was always its right Only for left-to-right (LTR) languages. For right-to-left (RTL) languages (e.g., Hebrew, Arabic), end is left

问题 I'm having a hard time getting two text views to appear on top of each other in my java code. Here's the code I'm experimenting with: /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); layout = new RelativeLayout(this); text1 = new TextView(this); text1.setText("1"); text2 = new TextView(this); text2.setText("2"); RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams

问题 In short, is it possible to tell a child in a RelativeLayout to always match the height of that RelativeLayout regardless of how other children in that same RelativeLayout behave? In short, that's it. Details below. What I'm trying to achieve is a ListView row with at least three views, and one of those views would be kind of a stripe at the right side of the list entry (the red view below). The problem I'm having is that there is a TextView at the left side, and depeding on how much text I

Here is my xml code : <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res

问题 I tried many times to draw 2 Relative layout aligned horizontally and divided in half screen. I design the image with paint to explain a bit better what i mean. Any suggestion? 回答1: You can put these 2 RelativeLayouts inside a LinearLayout with horizontal orientation, then use the weight for both RelativeLayouts. This will divide the LinearLayout in 2 equal parts. <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" android

问题 I'm adding two buttons to the UI, but they appear on top of one another. I want them to appear next to each other. What am I missing in this code? m_btnCrown = new ImageButton(this); m_btnCrown.setImageResource(R.drawable.king_crown_thumb); m_btnCrown.setAlpha(100); RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); lp.addRule(RelativeLayout.ALIGN_PARENT_TOP); addContentView(m_btnCrown, lp); m
