Android的ListView控件用不同的颜色 [英] Android ListView with different colors
本文介绍了Android的ListView控件用不同的颜色的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有在用不同的颜色有点问题的ListView 。
我已经试过几件事情，但似乎没有任何工作。
私有类GameRowAdapter扩展ArrayAdapter {
ArrayList的对象;
公共GameRowAdapter（上下文的背景下，INT textViewResourceId，ArrayList的＆LT; RowModel＆GT;对象）{
超（背景下，textViewResourceId，对象）;
this.objects =物体;
} @覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
查看排= convertView;
RowModelViews模型;
如果（行== NULL）{
LayoutInflater吹气= LayoutInflater.from（GamePlayerActivity.this）;
行= inflater.inflate（R.layout.game_line_layout，NULL）;
模型=新RowModelViews（）;
model.entry =（TextView中）row.findViewById（R.id.gameLineEntry）;
model.score =（TextView中）row.findViewById（R.id.gameLineEntryScore）;
row.setTag（模型）;
}其他{
模型=（RowModelViews）row.getTag（）;
} 如果（位置== || 6位== 7）{
row.setBackgroundColor（R.color.black）;
}其他{
row.setBackgroundColor（R.color.light_transparent）;
} model.entry.setText（objects.get（位置）.entry）;
model.score.setText（objects.get（位置）.score）; 返回行;
}
}静态类RowModelViews {
TextView的进入;
TextView的分数;}静态类RowModel {
字符串项;
字符串分; 公共RowModel（字符串输入，字符串分数）{
this.entry =条目;
this.score =得分;
}
}
任何人谁可以告诉我，我做错了？
感谢您。

解决方案
编辑：运行一个小的局部测试之后，我认为这个问题可能是你每行中有TextViews是在ListView行视图的前面。尝试将model.entry和model.score背景颜色。 /编辑
我认为这是从convertViews即将被重用。尝试移动这样的：
如果（位置== || 6位== 7）{
row.setBackgroundColor（R.color.black）;
}
在if（行== NULL）块的外面，改成这样：
如果（位置== || 6位== 7）{
model.entry.setBackgroundColor（R.color.black）;
model.score.setBackgroundColor（R.color.black）;}其他{
model.entry.setBackgroundColor（/ *无论您的默认背景颜色为* /）;
model.score.setBackgroundColor（/ *无论您的默认背景颜色为* /）;
}
所以，你完全getView方法是：
@覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
查看排= convertView;
RowModelViews模型;
如果（行== NULL）{
LayoutInflater吹气= LayoutInflater.from（GamePlayerActivity.this）;
行= inflater.inflate（R.layout.game_line_layout，NULL）;
模型=新RowModelViews（行）;
model.entry =（TextView中）row.findViewById（R.id.gameLineEntry）;
model.score =（TextView中）row.findViewById（R.id.gameLineEntryScore）;
row.setTag（模型）;
}其他{
模型=（RowModelViews）row.getTag（）;
} 如果（位置== || 6位== 7）{
model.entry.setBackgroundColor（R.color.black）;
model.score.setBackgroundColor（R.color.black）;
}其他{
model.entry.setBackgroundColor（/ *无论您的默认背景颜色为* /）;
model.score.setBackgroundColor（/ *无论您的默认背景颜色为* /）;
} model.entry.setText（objects.get（位置）.entry）;
model.score.setText（objects.get（位置）.score）; 返回行;
}
I am having a little problem using different colors in a ListView.
I have tried several things but nothing seems to work
private class GameRowAdapter extends ArrayAdapter { ArrayList objects;
public GameRowAdapter(Context context, int textViewResourceId, ArrayList<RowModel> objects) {
super(context, textViewResourceId, objects);
this.objects = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
RowModelViews model;
if (row == null) {
LayoutInflater inflater = LayoutInflater.from(GamePlayerActivity.this);
row = inflater.inflate(R.layout.game_line_layout, null);
model = new RowModelViews();
model.entry = (TextView) row.findViewById(R.id.gameLineEntry);
model.score = (TextView) row.findViewById(R.id.gameLineEntryScore);
row.setTag(model);
} else {
model = (RowModelViews) row.getTag();
}
if (position == 6 || position == 7) {
row.setBackgroundColor(R.color.black);
} else {
row.setBackgroundColor(R.color.light_transparent);
}
model.entry.setText(objects.get(position).entry);
model.score.setText(objects.get(position).score);
return row;
}
}
static class RowModelViews {
TextView entry;
TextView score;
}
static class RowModel {
String entry;
String score;
public RowModel(String entry, String score) {
this.entry = entry;
this.score = score;
}
}
Anyone who can tell me, what I am doing wrong?
Thank you.
UPDATE
Here is the xml of the inflatet row
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<TextView android:id="@+id/gameLineEntry"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_marginLeft="20dp"
android:textSize="20dp"
android:gravity="center_vertical"/>
<TextView android:id="@+id/gameLineEntryScore"
android:layout_height="fill_parent"
android:layout_width="65dp"
android:layout_marginRight="20dp"
android:gravity="center"
style="@style/Button"
android:layout_gravity="right"/>
</LinearLayout>
解决方案
Edit: After running a small local test, I think the issue may be that the TextViews you have in each row are in front of the ListView row view. Try setting the model.entry and model.score background colors. /Edit
I think it's coming from the convertViews being reused. Try moving this:
if (position == 6 || position == 7) {
row.setBackgroundColor(R.color.black);
}
Outside of the if (row == null) block, and change it to this:
if (position == 6 || position == 7) {
model.entry.setBackgroundColor(R.color.black);
model.score.setBackgroundColor(R.color.black);
} else {
model.entry.setBackgroundColor(/*Whatever your default background color is*/);
model.score.setBackgroundColor(/*Whatever your default background color is*/);
}
So your full getView method would be:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
RowModelViews model;
if (row == null) {
LayoutInflater inflater = LayoutInflater.from(GamePlayerActivity.this);
row = inflater.inflate(R.layout.game_line_layout, null);
model = new RowModelViews(row);
model.entry = (TextView) row.findViewById(R.id.gameLineEntry);
model.score = (TextView) row.findViewById(R.id.gameLineEntryScore);
row.setTag(model);
} else {
model = (RowModelViews) row.getTag();
}
if (position == 6 || position == 7) {
model.entry.setBackgroundColor(R.color.black);
model.score.setBackgroundColor(R.color.black);
} else {
model.entry.setBackgroundColor(/*Whatever your default background color is*/);
model.score.setBackgroundColor(/*Whatever your default background color is*/);
}
model.entry.setText(objects.get(position).entry);
model.score.setText(objects.get(position).score);
return row;
}
