如何通過選擇確定按鈕在警報對話框中啓動一個新的活動類

Question

用戶保存其細節時有第一個活動。點擊保存按鈕後，Alertdialog詢問關於確定或取消。如果用戶點擊確定，則新的活動開始。

protected final Dialog onCreateDialog(final int id) { 
    Dialog dialog = null; 
    switch(id) { 
    case DIALOG_ID: 
     AlertDialog.Builder builder = new AlertDialog.Builder(AppointInformation.this); 
     builder.setMessage("Information saved successfully ! Add Another Info?") 
     .setCancelable(false) 
     .setPositiveButton("No", new DialogInterface.OnClickListener() { 
public void onClick(DialogInterface dialog, int id) { 

startActivity(new Intent(((Dialog)dialog).getContext(),CheckPatient.class));  
      } 
     }) 
     .setNegativeButton("Yes", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int id) { 
       dialog.cancel(); 
      } 
     }); 
     AlertDialog alert = builder.create(); 
     dialog = alert; 
     break; 

    default: 

    } 
    return dialog; 
    } 

Answer 1

這應該做的伎倆

Intent intent = new Intent(this, NewActivity.class); 
startActivity(intent); 

Answer 2

在確定或取消按鈕，點擊就可以寫這篇文章，

Intent intent = new Intent(this, NewActivity.class); 
startActivity(intent); 

Answer 3

使用此代碼

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setMessage("Are you sure you want to exit?") 
    .setCancelable(false) 
    .setPositiveButton("Ok", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      Intent intent = new Intent(PresentActivity.this, NextActivity.class); 
      startActivity(intent); 
     } 
    }) 
    .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      dialog.cancel(); 
     } 
    }); 
builder.show(); 

Answer 4

做些什麼如下所示。

AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(AndroidAlertDialog.this); myAlertDialog.setTitle("--- Title ---"); 
     myAlertDialog.setMessage("Alert Dialog Message"); 
     myAlertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface arg0, int arg1) { 
     Intent intent = new Intent(this, NextActivity.class); 
     startActivity(intent); 
    }}); 

     myAlertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface arg0, int arg1) { 

     // do something when the Cancel button is clicked 
     }}); 

     myAlertDialog.show(); 

Answer 5

在你的代碼更改

：

startActivity(new Intent(((Dialog)dialog).getContext(),CheckPatient.class)); 

到

startActivity(new Intent(getBaseContext(),CheckPatient.class)); 

或

startActivity(new Intent(Activityname.this,CheckPatient.class)); 

Answer 6

AlertDialog.Builder alert = new AlertDialog.Builder(getApplicationContext()); 
    alert.setTitle(title); 
    alert.setCancelable(false); 
    alert.setMessage(message); 
    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      // TODO Auto-generated method stub 
      startActivity(new Intent(YourActivity.this, NewActivity.class)); 
     } 
    }); 
    alert.show(); 

使用上面的代碼:::

Answer 7

我知道一切都太遲了，但我想回答這個幫助別人，這個工作對我來說：

Intent intent = new Intent(getContext(),OtherActivity.class); 
       context.startActivity(intent); 

上下文是當前activiy的情況下。
