嘿,我正在制作一个简单的webview的Android应用程序。我想将用户重定向到某些网址上的浏览器。我想以对话框的形式显示一条消息,提醒用户他们正被重定向到他们的浏览器。用户将单击“确定”,然后重定向用户。
以下代码就是我所拥有的。问题是应用程序继续重定向,而不等待用户在对话框上单击“确定”。我希望应用程序仅在用户单击“确定”时暂停并继续任何活动。
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() { /*DialogInterface called while setting the AlertDialog Buttons */
public void onClick(DialogInterface dialog, int which) {
//Here you can perform functions of Alert Dialog Buttons as shown
switch (which){
case DialogInterface.BUTTON_POSITIVE:
//I want the app to pause here.
//MainActivity.this.onPause(); does not work
break;
}
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Title");// Set the Title of Alert Dialog
builder.setMessage("We are taking you to the admin page.").setPositiveButton("OK",dialogClickListener).show();
谢谢,我不想使用wait()因为我希望我的用户通过点击按钮来确认发生了什么
答案 0 :(得分:0)
试试这个:
public class MyClass extends Activity {
private boolean mustScan = true;
protected void onCreate(Bundle b) {
if (mustScan) {
// Just scan
// Note: If you use a Thread with a while loop, use this:
// while (true) {if (mustScan) {} }
}
}
// This is the method you use to show the Dialog
private void showResults (SomeResults here) {
// Show the dialog
// ...
mustScan = false;
// Also, in the OnClickListener of the buttons add "mustScan = true;"
}
