Answer 1

你需要使用活动或上下文，例如，请参考下面的代码

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(activity)
.setCancelable(false)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
activity.startActivity(new Intent(activity, DetailView.class));
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();

您可以从承包商获取活动或上下文。

Answer 2

更改这部分代码：

view.getContext().startActivity(new Intent(activity,DetailView.class));

对此：

Intent intent = new Intent(FirstActivity.this,Screen2Activity.class);
startActivity(intent);

完整代码：

alertDialogBuilder
.setCancelable(false)
.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String title = editTextTitle.getText().toString().trim();
String  r=android.get(i).getPassword();
if(title.equals(r)){
Intent intent = new Intent(FirstActivityName.this,Screen2ActivityName.class);
startActivity(intent);  
Toast.makeText(view.getContext()," user name   " , Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(view.getContext()," user name not valid  " , Toast.LENGTH_LONG).show();
}

// sendMessage(user.getId(), title, message);
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}
});
}
