问题描述
现在，我正在以编程方式创建视图，但它不起作用，我该怎么办？ b
相关代码
这是我的GridLayout
< android.support.v7.widget.GridLayout
android：id =@ + id / grd_team_a
android：layout_width =match_parent
android：layout_height =wrap_content
android：layout_margin =12dp
android：horizontalSpacing =1dp
app：columnCount =5
app：orientation = 水平 >
< TextView
android：id =@ + id / txtPlayersNameTi
android：text =Jugadores
android：textSize =14sp
android：paddingTop =5dp
android：paddingBottom =5dp
app：layout_columnWeight =2
app：layout_columnSpan =2
android：textStyle = 黑体/>
< TextView
android：text =Goles
android：gravity =center_horizontal
android：paddingRight =5dp
android：textSize =14sp
android：paddingTop =5dp
android：paddingBottom =5dp
app：layout_columnWeight =1
app：layout_columnSpan =1
android ：TEXTSTYLE = 黑体/>
< ImageView
android：src =@ drawable / ic_yellow_card_match
android：gravity =center_horizontal
android：textSize =14sp
android：paddingTop =5dp
android：paddingBottom =5dp
app：layout_columnWeight =1
app：layout_columnSpan =1
android：textStyle =bold/> ;
< ImageView
android：src =@ drawable / ic_red_card_match
android：gravity =center_horizontal
android：paddingTop =5dp
android：paddingBottom =5dp
app：layout_columnWeight =1
app：layout_columnSpan =1
android：textStyle =bold/>
< /android.support.v7.widget.GridLayout>
这是xml预览中的样子：
这是怎么样的数据：
但是，添加以下代码后：
int i = 2;
load = false;
GridLayout.Spec col2 = GridLayout.spec（2）;
GridLayout.Spec col3 = GridLayout.spec（3）;
GridLayout.Spec col4 = GridLayout.spec（4）;
GridLayout.Spec colspan2 = GridLayout.spec（0，1）;
grdTeamAPlayers.setColumnCount（5）;
grdTeamAPlayers.setRowCount（teamAPlayers.size（）+ 2）;
（TournamentPlayer newPlayer：teamAPlayers）
{
GridLayout.Spec row = GridLayout.spec（i）;
GridLayout.LayoutParams first = new GridLayout.LayoutParams（row，colspan2）;
GridLayout.LayoutParams goals = new GridLayout.LayoutParams（row，col2）;
GridLayout.LayoutParams yellow = new GridLayout.LayoutParams（row，col3）;
GridLayout.LayoutParams red = new GridLayout.LayoutParams（row，col4）;
TextView newName = new TextView（myContext）;
newName.setText（newPlayer.getName（）++ newPlayer.getLastName（））;
newName.setTextColor（ContextCompat.getColor（myContext，R.color.black_50））;
newName.setTextSize（14）;
newName.setLayoutParams（new LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.MATCH_PARENT））;
grdTeamAPlayers.addView（newName，first）;
TextView newGoals = new TextView（myContext）;
newGoals.setText（newPlayer.getGoals（）+）;
newName.setTextSize（14）;
newGoals.setTextColor（ContextCompat.getColor（myContext，R.color.black_50））;
newGoals.setLayoutParams（new LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.MATCH_PARENT））;
TextView newYellow = new TextView（myContext）;
newYellow.setText（newPlayer.getYellowCards（）+）;
newName.setTextSize（14）;
newYellow.setTextColor（ContextCompat.getColor（myContext，R.color.black_50））;
newYellow.setLayoutParams（new LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.MATCH_PARENT））;
TextView newRed = new TextView（myContext）;
newRed.setText（newPlayer.getRedCards（）+）;
newName.setTextSize（14）;
newRed.setTextColor（ContextCompat.getColor（myContext，R.color.black_50））;
newRed.setLayoutParams（new LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.MATCH_PARENT））;
grdTeamAPlayers.addView（newGoals，goals）;
grdTeamAPlayers.addView（newYellow，yellow）;
grdTeamAPlayers.addView（newRed，red）;
i = i + 1;
}
我得到的是这样的：
编辑：
是的，其他标题是消除了大白色的空间。
解决方案
所以，
尝试很多，花费大量的时间在这里工作：
GridLayout.LayoutParams doubleLayoutParams = new GridLayout.LayoutParams （）;
doubleLayoutParams.rowSpec = GridLayout.spec（i，1）;
// GridLayout.spec（rowNumber，rowSpan）;
doubleLayoutParams.columnSpec = GridLayout.spec（0，2f）;
// GridLayout.spec（columnNumber，columnSpan）;
TextView newName = new TextView（myContext）;
newName.setText（newPlayer.getName（）。trim（）++ newPlayer.getLastName（）。trim（））;
newName.setTextColor（ContextCompat.getColor（myContext，R.color.black_50））;
newName.setTextSize（12）;
newName.setEllipsize（TextUtils.TruncateAt.END）;
newName.setSingleLine（）;
newName.setWidth（0）;
grdTeamAPlayers.addView（newName，doubleLayoutParams）;
I have been trying to add views to a gridLayout, wich I have done, but they're not adjusting to the columns as they should, I had tried inflate the views with the same atribute that is showing well in XML but had no success.
Now, I am trying to create the views programatically but it isn't working, how can I achive what I want?
Relevant Code:
This is my GridLayout
<android.support.v7.widget.GridLayout
android:id="@+id/grd_team_a"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="12dp"
android:horizontalSpacing="1dp"
app:columnCount="5"
app:orientation="horizontal">
<TextView
android:id="@+id/txtPlayersNameTi"
android:text="Jugadores"
android:textSize="14sp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
app:layout_columnWeight="2"
app:layout_columnSpan="2"
android:textStyle="bold"/>
<TextView
android:text="Goles"
android:gravity="center_horizontal"
android:paddingRight="5dp"
android:textSize="14sp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
app:layout_columnWeight="1"
app:layout_columnSpan="1"
android:textStyle="bold"/>
<ImageView
android:src="@drawable/ic_yellow_card_match"
android:gravity="center_horizontal"
android:textSize="14sp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
app:layout_columnWeight="1"
app:layout_columnSpan="1"
android:textStyle="bold"/>
<ImageView
android:src="@drawable/ic_red_card_match"
android:gravity="center_horizontal"
android:paddingTop="5dp"
android:paddingBottom="5dp"
app:layout_columnWeight="1"
app:layout_columnSpan="1"
android:textStyle="bold"/>
</android.support.v7.widget.GridLayout>
This is how it looks like in the xml preview:
And this is how it should like with data:
But, after adding with this code:
int i = 2;
loading=false;
GridLayout.Spec col2 = GridLayout.spec(2);
GridLayout.Spec col3 = GridLayout.spec(3);
GridLayout.Spec col4 = GridLayout.spec(4);
GridLayout.Spec colspan2 = GridLayout.spec(0, 1);
grdTeamAPlayers.setColumnCount(5);
grdTeamAPlayers.setRowCount(teamAPlayers.size()+2);
for(TournamentPlayer newPlayer: teamAPlayers)
{
GridLayout.Spec row = GridLayout.spec(i);
GridLayout.LayoutParams first = new GridLayout.LayoutParams(row, colspan2);
GridLayout.LayoutParams goals = new GridLayout.LayoutParams(row, col2);
GridLayout.LayoutParams yellow = new GridLayout.LayoutParams(row, col3);
GridLayout.LayoutParams red = new GridLayout.LayoutParams(row, col4);
TextView newName = new TextView(myContext);
newName.setText(newPlayer.getName() + " " + newPlayer.getLastName());
newName.setTextColor(ContextCompat.getColor(myContext, R.color.black_50));
newName.setTextSize(14);
newName.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
grdTeamAPlayers.addView(newName, first);
TextView newGoals = new TextView(myContext);
newGoals.setText(newPlayer.getGoals() + "");
newName.setTextSize(14);
newGoals.setTextColor(ContextCompat.getColor(myContext, R.color.black_50));
newGoals.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
TextView newYellow = new TextView(myContext);
newYellow.setText(newPlayer.getYellowCards() + "");
newName.setTextSize(14);
newYellow.setTextColor(ContextCompat.getColor(myContext, R.color.black_50));
newYellow.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
TextView newRed = new TextView(myContext);
newRed.setText(newPlayer.getRedCards()+"");
newName.setTextSize(14);
newRed.setTextColor(ContextCompat.getColor(myContext, R.color.black_50));
newRed.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
grdTeamAPlayers.addView(newGoals, goals);
grdTeamAPlayers.addView(newYellow, yellow);
grdTeamAPlayers.addView(newRed, red);
i=i+1;
}
What I get is this:
EDIT:
Yes, the other titles are dissapering and the big white space is showing.
解决方案
So, Trying a lot, and spending a lot of time finnally work with this:
GridLayout.LayoutParams doubleLayoutParams = new GridLayout.LayoutParams();
doubleLayoutParams.rowSpec = GridLayout.spec(i,1);
// GridLayout.spec(rowNumber,rowSpan);
doubleLayoutParams.columnSpec = GridLayout.spec(0, 2f);
// GridLayout.spec(columnNumber,columnSpan);
TextView newName = new TextView(myContext);
newName.setText(newPlayer.getName().trim() + " " + newPlayer.getLastName().trim());
newName.setTextColor(ContextCompat.getColor(myContext, R.color.black_50));
newName.setTextSize(12);
newName.setEllipsize(TextUtils.TruncateAt.END);
newName.setSingleLine();
newName.setWidth(0);
grdTeamAPlayers.addView(newName, doubleLayoutParams);
