任何人都可以請指導我如何setOnClickListener動態生成的TextViews。 我的應用程序中有幾個按鈕。現在當單擊某個特定按鈕時,將根據返回的元素數量從數據庫中檢索某些特定文本元素,以生成相應的TextView以顯示檢索到的文本元素。 現在我遇到的問題是,我不知道如何爲動態生成的TextView設置onClickListner。以下是我創建TextView的代碼片段。請指導我該怎麼做.thank你如何爲onClickListener設置動態生成的textviews?
public void onClick(View v) {
switch (v.getId()) {
case R.id.imageButton1:
catagory = "General";
IndependentDB genData = IndependentDB.getInstance();
genData.open(this);
ArrayList<TextHolder> genList = new ArrayList<TextHolder>();
genList = genData.getAllTextFromGenT();
genData.close();
x = genList.size();
String xstr = new StringBuilder().append(x).toString();
System.out.println(xstr);
mainText = new TextView[x];
textLayout = new LinearLayout[x];
llseperator = new LinearLayout[x];
textLayoutContainer
.setBackgroundResource(R.color.dark_navy_blue);
if (!genList.isEmpty()) {
for (int i = 0; i < x; i++) {
TextHolder firstOne = genList.get(i);
String text = firstOne.getText();
mainText[i] = new TextView(this);
mainText[i].setId(i);
mainText[i].setText("Text");
mainText[i].setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
mainText[i].setTextSize(25);
mainText[i].setGravity(Gravity.CENTER);
mainText[i].setText(text);
mainText[i].setTextColor(0xFFFFFFFF);
mainText[i].setClickable(true);
mainText[i].setOnClickListener(this);
llseperator[i] = new LinearLayout(this);
llseperator[i].setId(i);
llseperator[i].setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
llseperator[i].setGravity(Gravity.CENTER);
llseperator[i]
.setBackgroundResource(R.drawable.tv_seperator);
textLayout[i] = new LinearLayout(this);
textLayout[i].setId(i);
textLayout[i].setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
textLayout[i].setGravity(Gravity.CENTER);
textLayout[i].addView(mainText[i]);
textLayoutContainer.addView(textLayout[i]);
textLayoutContainer.addView(llseperator[i]);
}// End of for
}// End of If
break;}
謝謝你的答覆。好吧要試試這個,看看它是否有效。 – Viking 2012-01-18 04:11:00
