我有以下方法，我想显示一个 Snackbar。问题是，我没有 Activity view，而且我不知道如何获取它。在代码中，您会看到 Snackbar view 是 viewInflate_setup 但它不起作用。我知道它不起作用，因为这是我的 alertdialog View ，而不是我当前的屏幕。我已经尝试获取 root view 但随后 snackbar 显示在错误的位置(在这三个 android 按钮后面)。如何获取我的 Activity View？
public void confirmPassword(){
final LayoutInflater inflateSetup = getLayoutInflater();
final View viewInflate_setup = inflateSetup.inflate(R.layout.inflate_setup, null);
AlertDialog.Builder alertSetup = new AlertDialog.Builder(this);
alertSetup.setView(viewInflate_setup);
final AlertDialog dialogSetup = alertSetup.create();
dialogSetup.show();
btnConfirmPassowod = (Button)viewInflate_setup.findViewById(R.id.btnConfirm);
btnConfirmPassowod.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
System.out.println("User has clicked the [confirm] button");
dialogSetup.setCancelable(false);
edtPassword3 = (EditText)viewInflate_setup.findViewById(R.id.edtPassword3);
SUpassword3 = edtPassword3.getText().toString();
final ParseUser beforeConfirmPassword = ParseUser.getCurrentUser();
ParseUser.logInInBackground(beforeConfirmPassword.getUsername(), SUpassword3, new LogInCallback() {
@Override
public void done(ParseUser parseUser, ParseException e) {
if(e==null){
//password confirmed, go to next setup
System.out.println("Password [" +SUpassword3+ "] and user [" +beforeConfirmPassword.getUsername()+ "] confirmed, go to setup");
dialogSetup.dismiss();
}else{
//passwords don't match
System.out.println("Password don't match: [" +SUpassword3 + "] USER [" +beforeConfirmPassword.getUsername()+ "]");
Snackbar.make(viewInflate_setup, "Wrong password. Try again.", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
dialogSetup.dismiss();
}
}
});
}
});
}
