relativelayout

问题 I don't know why, but layout is shown well on device with Api 11+, isn't for older. This is xml: <LinearLayout android:id="@+id/workers_linearlayout" android:layout_width="50dp" android:layout_height="70dp" android:layout_weight="1" > <RelativeLayout android:id="@+id/workers_relative_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap

问题 I have a little problem defining a Relative Layout. I have a List View with scroll and two buttons always visible at the bottom of the list view. I just would like my two button have 50% of the width, filling the line. This is my code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <Button android:id="@+id/testbutton"

问题 I have a problem with this layout and i cannot find out what is wrong. As you can see, there is a chronometer and a table inside a relative layout but the chronometer does not show, not even a blank space. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/firstLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Chronometer android:id="@+id/chrono" android:textColor="#4169E1" android

问题 The question is: I have a TextView and an EditText, how can I place them on the same "level"? http://postimage.org/image/o9l17a3zv/ As you can see, I want to put "Username" on the same level of the EditText... Here my code: <TextView android:id="@+id/account_creation" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/account_creation" android:textSize="20sp" android:textStyle="bold" /> <!-- Username --> <TextView android:id="@+id/username

问题 I'm trying to add multiple layouts dynamically under each other. So I wrote the following code: for (int i = 1; i <= layoutCounter; i++) { View neu = inflater.inflate(R.layout.vote, parent, false); neu.setId(layoutID); if (layoutID == 1) { params = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); params.addRule(RelativeLayout.BELOW, R.id.txtMultiline); } else { params = new RelativeLayout.LayoutParams( RelativeLayout

问题 I came across this link : Assign width to half available screen width declaratively How to do the same in relative layout? Here's the code: Trying linearlayout inside relative layout. But this doesn't work. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/bg" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent"

问题 I have a ScrollView on one of my screens. I want the right edge to have a shadow. I decided the easiest way to do this was to make the child of the ScrollView a RelativeLayout, and have two children of the RelativeLayout -- one being a LinearLayout that will house the layout of the screen, and the second View being the shadow. Like so... <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" android:scrollbars="none" > <RelativeLayout android:layout_width="fill

问题 I want to implement grid, which will be populated dynamically. I want to know what is the best approach to implement this Relative layout(List View) or Grid Layout? 回答1: You can generate a GridView dynamically. GridView would contain of ImageView and TextView as per your need. You will have to use your custom adapter. In it's getView method, populate the ImageView and TextView. Example: GridView item.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout

问题 I want to do something like this programmatically - <LinearLayout> <RelativeLayout1 weight = 1> <RelativeLayout2 weight = 3> <RelativeLayout3 weight = 1> <LinearLayout> It does not let me do a setWeight programmatically. However, I do see that RelativeLayout has an android:layout_weight parameter in XML. Am I missing something? 回答1: When you add the RelativeLayout to the LinearLayout using addView you have to provide a LinearLayout.LayoutParams, something like this : LinearLayout.LayoutParams
