如何防止我的对话框扩展活动?
当我在我的主要活动中创建它时,当我单击“确定”时它不会自行关闭,这会创建一个新活动。创建的新活动从 MainActivity 扩展。
我正在使用共享首选项来确定在用户打开应用程序时将其发送到哪里。我不确定这是否会影响这种情况。
我想阻止对话框扩展 MainActivity。它不应该出现在我创建的其他活动中。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SharedPreferences sharedPreferences = getSharedPreferences("version", 0);
int savedVersionCode = sharedPreferences.getInt("VersionCode", 0);
int appVershionCode = 0;
try { appVershionCode = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode; }
catch (NameNotFoundException nnfe) { Log.w(TAG, "$ Exception because of appVershionCode : " + nnfe); }
if(savedVersionCode == appVershionCode){
// Returning user
Log.d(TAG, "$$ savedVersionCode == appVershionCode");
// Temporary Navigation
final Builder alertDialogBuilder = new Builder(this);
new AlertDialog.Builder(new ContextThemeWrapper(getBaseContext(), android.R.style.Theme_Dialog));
alertDialogBuilder.setTitle("Temporary Navigation");
alertDialogBuilder.setMessage("Go to the new activity.");
alertDialogBuilder.setPositiveButton("Okay", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Log.d(TAG, "$$ onClick");
Intent newactivity = new Intent(MAINACTIVITY.this,NEWACTIVITY.class);
startActivity(newactivity);
dialog.cancel();
}
});
alertDialogBuilder.show();
// End
} else {
// First time visitor
Log.d(TAG, "$$ savedVersionCode != appVershionCode");
// Hide graphics meant for returning users
((Button)findViewById(R.id.Button01)).setVisibility(View.INVISIBLE);
SharedPreferences.Editor sharedPreferencesEditor = sharedPreferences.edit();
sharedPreferencesEditor.putInt("VersionCode", appVershionCode);
sharedPreferencesEditor.commit();
Builder alertDialogBuilder = new Builder(this);
alertDialogBuilder.setTitle("Welcome");
alertDialogBuilder.setMessage("Click Okay to continue.");
alertDialogBuilder.setNeutralButton("Okay", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Log.d(TAG, "$$ onClick");
Intent leagues = new Intent(MAINACTIVITY.this,NEWACTIVITY.class);
startActivity(leagues);
}
});
alertDialogBuilder.show();
}
}
