Ich versuche, ein Edittext-Feld in einem Dialogfeld zur Eingabe eines Passworts zu erstellen. und wenn ich es tue, kann ich es nicht tun. Ich bin ein Anfänger darin. Bitte helfen Sie mir dabei.
public class MainActivity extends Activity {
Button create, show, setting;
//String pass="admin";String password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
create = (Button)findViewById(R.id.amcreate);
setting = (Button)findViewById(R.id.amsetting);
show = (Button)findViewById(R.id.amshow);
//input = (EditText)findViewById(R.id.this);
setting.setVisibility(View.INVISIBLE);
create.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent1 = new Intent(view.getContext(), Create.class);
startActivityForResult(myIntent1, 0);
}
});
show.setOnClickListener(new View.OnClickListener() {
//@SuppressWarnings("deprecation")
public void onClick(final View view) {
// Creating alert Dialog with one Button
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
//AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
// Setting Dialog Title
alertDialog.setTitle("PASSWORD");
// Setting Dialog Message
alertDialog.setMessage("Enter Password");
**final EditText input = new EditText(this);**
//alertDialog.setView(input);
// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.key);
// Setting Positive "Yes" Button
alertDialog.setPositiveButton("YES",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
// Write your code here to execute after dialog
Toast.makeText(getApplicationContext(),"Password Matched", Toast.LENGTH_SHORT).show();
Intent myIntent1 = new Intent(view.getContext(), Show.class);
startActivityForResult(myIntent1, 0);
}
});
// Setting Negative "NO" Button
alertDialog.setNegativeButton("NO",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Write your code here to execute after dialog
dialog.cancel();
}
});
// closed
// Showing Alert Message
alertDialog.show();
}
});

Überprüfen Sie diese developer.android.com/guide/topics/ui/notifiers/toasts.html . Positionieren Sie die Toasts. Aber ich denke, es ist besser, für edittext
