Our problem is we need to make some kind of a menu where on the first activity there is a list of food with checkboxes.
What we wanted to do is when the onClickmeal_ok button is clicked, the information in the checkboxes that were checked will be displayed in another activity.
This is our .xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:background="#ffff"
tools:context=".MainMenu" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="#string/dessertsmenu"
android:textAppearance="?android:attr/textAppearanceLarge" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginRight="27dp"
android:text="#string/meal_ok"
android:onClick="onClickmeal_ok" />
<CheckBox
android:id="#+id/chkAutosave3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/chkAutosave1"
android:layout_below="#+id/chkAutosave1"
android:defaultValue="false"
android:text="#string/peachcrumbbars"
android:onClick="onClickpeachcrumbbars_ok" />
<CheckBox
android:id="#+id/chkAutosave4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/chkAutosave3"
android:layout_below="#+id/chkAutosave3"
android:defaultValue="false"
android:text="#string/snickerysquares"
android:onClick="onClicksnicjerysquares_ok" />
<CheckBox
android:id="#+id/chkAutosave1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/textView1"
android:layout_below="#+id/textView1"
android:layout_marginLeft="22dp"
android:layout_marginTop="18dp"
android:defaultValue="false"
android:text="#string/blackberrypiebars"
android:onClick="onClickblackberrypiebars_ok" />
and this is our .java file:
package net.xadtv.yoursmenu;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class DessertsMenu extends Activity{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.desserts);
}
public void onClickblackberrypiebars_ok(View view) {
}
public void onClickpeachcrumbbars_ok(View view) {
}
public void onClicksnicjerysquares_ok(View view) {
}
public void onClickmeal_ok(View view) {
}
}
To pass data between activies use Intent extra,
public void onClickmeal_ok(View view)
{
Intent i = new Intent("com.example.activityname");
i.putExtra("extra1", "this is an extra");
i.putExtra("extra2", 420);
}
You can also use Bundle to put multiple items at once
public void onClickmeal_ok(View view)
{
Intent i = new Intent("com.example.activityname");
Bundle extras = new Bundle();
extras.putInt("extra4", 420);
i.putExtras(extras);
}
Then you can retrieve data by using
String stringExtra1 = getIntent().getString("extra1");
or retrieve the whole bundle with
Bundle bundle = getIntent().getExtras();

How to pass a value from one Activity to another in Android?

Closed 7 years ago.
This is my 1st time working in AndroidStudio. What I want to do is I want to pass the value generated in the txresult(activity_main.xml), the one generated after it scans. I want to pass that value after I push Yes, to my SecondActivity.java, and to be able to display the value.

Using Intent.putExtra() you can do what you want to do.
Intent intent = new Intent( this, MyActivity.class );
intent.putExtra( "paramName", textview.getText().toString() );
startActivity( intent );
You can get the values by using
Bundle extras = getIntent().getExtras();
if (extras != null)
{
String myParam=extras.getString("paramName");
}
You would use this part on the second activity, specifically the onCreate methode.
Try this:
Intent i=new Intent(MainActivity.this, SecondActivity.class);
i.putExtra("result",txResult.getText());
startActivity(i);
and in your SecondActivity:
Bundle extras = getIntent().getExtras();
if (extras != null)
{
String strResult=extras.getString("result");
}
strResult gives your string passed from your previous Activity
FirstActivity.java
public class FirstActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.first_activity);
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView textView = (TextView) findViewById(R.id.text_view);
Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("textViewText", textView.getText().toString());
startActivity(intent);
}

}
public OnClickListener signUpListener=new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent(MainActivity.this,Welcome.class));
}
};
}
You have to setOnTouchListener to the TextView. Here I give you an example:
public class MainActivity extends Activity implements View.OnTouchListener {
private TextView tv1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv1 = (TextView) findViewById(R.id.tv1);
tv1.setOnTouchListener(this);
}
#Override
public boolean onTouch(View v, MotionEvent event) {
// HERE YOU HAVE TO CHECK WHICH ID IS SELECTED, IF YOU HAVE MORE THAN ONE,
// AND WHICH EVENT HAS THE USER DONE.
// IN YOUR CASE.. OPEN WEBSITE LIKE THIS:
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
return true;
}
}
you can try Linkify here
textview.setText("www.androiddeveloper.com");
Linkify.addLinks(textview, Linkify.WEB_URLS);

And here is where I am trying to change it to VISIBLE in the code.
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.ProgressBar;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
//Get Views and Buttons
EditText txt_Username = (EditText) findViewById(R.id.txtView_UserName);
EditText txt_Password = (EditText) findViewById(R.id.txtView_Password);
Button btn_LogIn = (Button) findViewById(R.id.button_LogIn);
CheckBox chkbox_RememberMyPassword = (CheckBox) findViewById(R.id.checkbox_RememberPassword);
CheckBox chkbox_LogMeInAutomatically = (CheckBox) findViewById(R.id.checkbox_LogMeInAutomatically);
ProgressBar progressbar_LogIn = (ProgressBar) findViewById(R.id.progressBar_LogIn);
public void logIn() {
progressbar_LogIn.setVisibility(0);
}
}
The program is crashing without rendering my Activity's Views. Any ideas?
I have a feeling its because you have an onClick for login, but login doesn't take a view parameter. Try setting the onclick for the button programmatically, instead of using the xml.
Edit: Try changing
public void logIn() {
progressbar_LogIn.setVisibility(0);
}
to
public void logIn(View v) {
progressbar_LogIn.setVisibility(0);
}
or to set it programatically
btn_LogIn.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View arg0) {
//CODE GOES HERE
}
});
Further Edit:
Also noticed that theres no sign of an onCreateView so make sure that all that view code is inside of, or atleast inside of onCreate:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
}

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView img = (ImageView)findViewById(R.id.imageView1);
img.setClickable(true);
OnClickListener l;

I need the application to pass some string value associated to it to be passed into the text as soon as the user clicks on the image.How do i use the click Listeners in android to achieve the following task.
It is not necessary to fill in the code snippet that i have given.Any new ideas regarding the design are most welcome.
U can set text as Tag to the Image so that u can get that text onClick event. Tag can be set either in XML or dynamically.
public class TrialActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView img = (ImageView)findViewById(R.id.imageView1);
img.setTag("YOur text");
img.setClickable(true);
img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
String urText= arg0.getTag().toString();
EditText edt = (EditText)findViewById(R.id.editText1);
edt.setText(urText);
}
});
}
}
This code demonstrates how to achieve your requirement dynamically.

Call startActivity() on "a separate class activity", passing whatever data you want (such as the ZXing results) via extras on the Intent you supply to startActivity(). Your "separate class activity" can then use getIntent() to retrieve the Intent and the various get...Extra() methods to retrieve those values.
