Question

Okay so im having a hard time saving the state of my activity so that when the activity is destroyed it can restore where the user last left off. Here is my source code. If anyone could look at it and tell me how i would save and restore is please it will be greatly appreciated.

Here is my code…

                public class DorothyTalk extends Activity{
    Handler handler = new Handler();
    int typeBar;
TextView text1;
EditText edit;
Button respond;
private String name;
private ProgressDialog progDialog;
@Override 
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dorothydialog);

    text1 = (TextView)findViewById(com.fttech.da.R.id.dialog);
    edit = (EditText)findViewById(com.fttech.da.R.id.repsond);
    respond = (Button)findViewById(com.fttech.da.R.id.button01);

    Talk();

}

    protected Dialog onCreateDialog(int id) {
switch(id) {
case 0:                      // Spinner
    progDialog = new ProgressDialog(this);
    progDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    progDialog.setMessage("Loading...");
    progDialog.setProgress(100);

    return progDialog;

}
return progDialog;
}
public void Talk(){

    text1.setText("Welcome what is your name?");

    respond.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            name = edit.getText().toString();
            new AsyncTask<Void, Integer, Void>(){

            @Override
        protected Void doInBackground(Void... arg0) {
            try {                 
             Thread.sleep(1000);             
            } catch (InterruptedException e) {                         
                e.printStackTrace();             
                    }            
                    return null;
            }
            @Override         
        protected void onPostExecute(Void result) {             
                    text1.setText("Nice to meet you "+name);
                    dismissDialog(typeBar);
                     }


                @Override        
        protected void onPreExecute() { 
            typeBar = 0;
        showDialog(typeBar);

        }

        }.execute((Void)null);

        }
    });
    }


    public void onBackPressed()
      {
        int i = Log.d("CDA", "onBackPressed Called");
        Context localContext = getApplicationContext();
        Intent localIntent = new Intent(localContext, mainMenu.class);
        startActivityForResult(localIntent, 0);

        return;




    }

How can i save and restore when activity is destroyed?

Answer 1

You have to save your data before your activity is destroyed. You can test if it is going to be destroyed by using the isFinishing()

protected void onPause(){
if(isFinishing()){
saveData();
}
}

then you neeed to reload your data onCreate()
