我有一個顯示分項疊加的mapview,每個onTap事件顯示一個對話框,其中包含關於旅行社和三個按鈕的信息,其中一個應該在瀏覽器中打開代理網站,但是當我點擊我得到的按鈕時:找不到處理意圖的活動。Android從對話框中啓動瀏覽器
這裏是我的代碼:
protected boolean onTap(int i){
float[] results = new float[1];
Location.distanceBetween(decdegrees(appState.getMyLocation().getLatitudeE6()), decdegrees(appState.getMyLocation().getLongitudeE6()), decdegrees(points.get(i).getPoint().getLatitudeE6()), decdegrees(points.get(i).getPoint().getLongitudeE6()), results);
float distance = results[0]/1000;
DecimalFormat maxDigitsFormatter = new DecimalFormat("#.#");
String infos=points.get(i).getSnippet() + "#" + String.valueOf(maxDigitsFormatter.format(distance));
final String [] AInfos = infos.split("#");
final Dialog ADialog = new Dialog(c);
ADialog.setContentView(R.layout.travelagency);
TextView txtAgence = (TextView)ADialog.findViewById(R.id.txtAgence);
TextView txtAddress = (TextView)ADialog.findViewById(R.id.txtAddress);
TextView txtDistance = (TextView)ADialog.findViewById(R.id.txtDistance);
TextView txtFax = (TextView)ADialog.findViewById(R.id.txtFax);
Button btnCall = (Button)ADialog.findViewById(R.id.btnCall);
Button btnWebSite = (Button)ADialog.findViewById(R.id.btnWebSite);
Button btnCancel = (Button)ADialog.findViewById(R.id.btnCancel);
ADialog.setTitle(AInfos[0]);
btnCall.setText("Appeler : " + AInfos[2]);
txtAgence.setText(AInfos[1]);
txtDistance.setText("Approximativement à : " +AInfos[6] + " Km");
txtAddress.setText("Adresse : " + AInfos[3]);
txtFax.setText("Fax : " + AInfos[4]);
ADialog.show();
btnCancel.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
ADialog.dismiss();
}
});
btnWebSite.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent myIntent = new Intent(Intent.ACTION_VIEW,Uri.parse(AInfos[5]));
v.getContext().startActivity(myIntent);
}
});
return (true);
}
我發現的例子here和here但suddently不是爲我工作..
感謝
是我沒有看到它的代碼,「btnWebSite.setOnClickListener(新OnClickListener(){ 公共無效的onClick(視圖v){ 意圖myIntent =新意圖(Intent.ACTION_VIEW,Uri.parse(AInfos [5]) ); v.getContext()。startActivity(myIntent); } });'如果我刪除v.getContext它會導致其他錯誤 – Houssem 2011-04-22 10:51:36
調試應用程序,並確保AInfos [5]是一個網址 – 2011-04-22 10:55:28
你是對的AInfos [5]是空值,所以當我通過正確的網址,它的作品,但與此:v.getContext()。startActivity(myIntent)非常感謝你 – Houssem 2011-04-22 11:07:48
