Android中使用ListView实现漂亮的表格效果(7)
mStockListCursor.moveToPosition(position);
if (null == convertView) {
String code = mStockListCursor.getString(sCodeIndex);
String symbol = mStockListCursor.getString(sSymbolIndex);
String board = mStockListCursor.getString(sBoardIndex);
float lastPrice = mStockListCursor.getFloat(sLastPriceIndex);
float changePrice = mStockListCursor.getFloat(sChangePriceIndex);
float changePercent = mStockListCursor
.getFloat(sChangePricePercentIndex);
listItem = new StockListItem(mContext, code, symbol, board,
lastPrice, changePrice, changePercent);
} else {
listItem = (StockListItem) convertView;
}
return listItem;
}
}
StockListItem.java
package com.android.msoft.mfinance.ui;
import com.android.msoft.mfinance.R;
import android.content.Context;
import android.view.LayoutInflater;
import android.widget.LinearLayout;
import android.widget.TextView;
public class StockListItem extends LinearLayout {
public StockListItem(Context context, String code, String symbol,
String board, float lastPrice, float changePrice,
float changePercent) {
super(context);
StockListActivity stockListActivity = (StockListActivity) context;
float textSize = stockListActivity.getTextSize();
LayoutInflater factory = LayoutInflater.from(context);
factory.inflate(R.layout.stock_list_item, this);
TextView codeTextView = (TextView) findViewById(R.id.stock_code);
codeTextView.setTextSize(textSize);
codeTextView.setText(code);
TextView symbolTextView = (TextView) findViewById(R.id.stock_symbol);
symbolTextView.setTextSize(textSize);
symbolTextView.setText(symbol);
TextView lastPriceTextView = (TextView) findViewById(R.id.stock_last_price);
lastPriceTextView.setTextSize(textSize);
lastPriceTextView.setText(Float.toString(lastPrice));
TextView changePriceTextView = (TextView) findViewById(R.id.stock_change_price);
changePriceTextView.setTextSize(textSize);
changePriceTextView.setText(Float.toString(changePrice));
TextView ChangePercentTextView = (TextView) findViewById(R.id.stock_change_percentage);
ChangePercentTextView.setTextSize(textSize);
ChangePercentTextView.setText(Float.toString(changePercent));
if (changePrice > 0) {
int textColor = stockListActivity.getUpTextColor();
// codeTextView.setTextColor(textColor);
// symbolTextView.setTextColor(textColor);
lastPriceTextView.setTextColor(textColor);
changePriceTextView.setTextColor(textColor);
ChangePercentTextView.setTextColor(textColor);
}
else if (changePrice < 0)
{
int textcolor="stockListActivity.getDownTextColor(); codetextview.settextcolor(textcolor);
symboltextview.settextcolor(textcolor);
lastpricetextview.settextcolor(textcolor); changepricetextview.settextcolor(textcolor);
changepercenttextview.settextcolor(textcolor)
}
}
}
到此就大功告成了，这个例子我们是通过View来画线条分割各个单元格的，另外我们还可以通过定义不同的背景色，通过背景色来达到相似的效果，这个不难，就不写了。
