Can any one tell me how to pass the value from one screen to its previous screen. Consider the case.i m having two screen first screen with one Textview and button and the second activity have one edittext and button.
If i click the first button then it has to move to second activity and here user has to type something in the textbox. If he press the button from the second screen then the values from the textbox should move to the first activity and that should be displayed in the first activity textview.
This is passing Values from one activity to another
i want to pass the text with same FontStyle, Color and Size of the font.
Use the same style,color and size for first activity TextView and second Activity's EditTextView.
If you are done it with programming, then just pass the other parameters also with the intents, and set it in the first activity's TextView.
Like,
intent.putExtra("fontStyle","American Dream");
intent.putExtra("color","value");
intent.putExtra("size","value");
Use this in first activity to set TextView's properties.
String fontStyle = getIntent().getExtras().getString("fontStyle");
String fontColor = getIntent().getExtras().getString("color");
String fontSize = getIntent().getExtras().getString("size");
Typeface font2 = Typeface.createFromAsset(getApplicationContext().getAssets(),"fonts/"+fontStyle+".ttf");
// here fontStyle is string which you passed from the second Activity
textView.setTypeface(font2);
Also, you can do this onClick
SecondButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
TextView text= (TextView) findViewById(R.id.textview);
text.settext(Edittext.getText());
Intent intent= new Intent(form2.this, form1.class);
startActivity(intent);
}
});

i have a problem
i have button A in first activity and button B in second activity,i want when someone click button B in second activity then color of A button is change permanently it never reverse to previous colour again when ever user not uninstall the app
This is not how you ask a question in SO, you should try something first and when you hit a problem, then you can ask your question as specific you can, along with all things you have done. you can read about how you can ask a good question in here.
Now you can try something like this:
//create a method in your first activity, (where the button color should change):
public void changeColorInFirstActivity(){
Button btnA = (Button) findViewById(R.id.myButtonA);
btnA.setBackgroundColor(getResources().getColor(R.color.red));
}
And add this in your second activity where you want to click on a button to change the first activity button color:
Button btnB = (Button) findViewById(R.id.myButtonB);
btnB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FirstActivity secondActivity = new FirstActivity();
firstActivity.changeColorInFirstActivity();
}
});
Now after setting the color, save the color int in shared preferences and set the value you get on your button color in your First activity
I want to know how I could change a buttons backgroundresource that mimics another button's background resource so that whenever I change that button's backgroundresource it another button mimics the looks of the first button...
for example:
int icon = R.drawable.ic_icon; //more specifically I stored R.drawable.ic_icon in SQL and retrieve and save in int icon when retrieve from that table, so when the table is change the first button dynamically change on create;
btn_01.setBackgroundResource(icon); //when this button is pressed it inflates a layout containing btn_02
btn_02.setBackgrounResource(??????); //this button is on a different layout and is used by different activity and should take the backgroundresource of the button that have been pressed to call that layout.
I could use if else statement but I have different button to be copied by the second button and each button has different backgroundresource possibility.
I couldn't understand your question fully but anyways here is what I got
You can put the resource id in the Intent before starting the activity when Btn_01 is clicked.
Btn_01.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(this,Activity2.class);
intent.putExtra("resource_key", R.drawable.ic_heart);
startActivity(intent);
}
});
then in your Activity2 you can just get your resource data and set to whatever button you want
int DEFAULT_RESOURCE = R.drawable.ic_close;
int resourceId = getIntent().getIntExtra("resource_key",DEFAULT_RESOURCE);
Btn_02.setBackgroundResource(resourceId);
As the title states, I am looking to find out how to create a button dynamically when another button in another activity is pressed. This is being done with the Android SDK.
Basically, I have two activities, MainActivity and SecondaryActivity, within the SecondaryActivity you enter some information, title, text, id, so on and so forth. When you click the "Save" button it sends some, information to MainActivity(not the issue). As well as sending the information, I need to create an entirely new button within the MainActivity.
Any suggestions on how this should be accomplished?
Thanks.
Edit 1
public void CreateNewButton(View view)
{
LinearLayout lineLayout = (LinearLayout)findViewById(R.id.linear_layout);
TextView newTextView = new TextView(this);
int id = rand.nextInt(100);
int newId;
newTextView.setVisibility(View.VISIBLE);
newTextView.setId( R.id.new_button + id );
newTextView.setText("New Item");
newTextView.setTextSize(35);
newTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
intent = new Intent(getBaseContext(), SecondActivity.class);
startActivity(intent);
}
});
lineLayout.addView(newTextView);
}
This code generates the new TextView( Decided to change it up ) but now the issue I have, is newTextView.setText(); needs to get the text from the other activity
newTextView.setText(i.getData().toString());
putting this in the CreateNewButton(View view) methods causes an error since technically there is no data in the field that it is trying to grab from.
The problem at hand is I need to create the new TextView field WITH the name of the new account that has yet to be created. If that makes any sense.
I'm going to assume you want to add this button to a LinearLayout:
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linearLayout1);
Button button = new Button(this);
button.setText("I'm a button!");
// add whatever other attributes you want to the button
linearLayout.addView(button);
I'm a newbie here, sorry for the dumb question. I am trying to display an image in drawables that is equal value with the text inputted in edittext.
For example I input "A" and a certain image will appear in the next activity after I click done.
My personal idea is that, this will be done in imageview, but how about if I enter "ABC" and 3 images equal to the inputted text will appear simultaneously.
I think array will be use in this problem but I have no idea how to start.
ImageView image = (ImageView) findViewById(R.id.iamgeActivity);
image.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//my problem starts here
}
});
If I got you right..you can do it like in first activity, on clicking done button take the name of image from editText to next activity through bundle.
Intent intent= new Intent(currentactivity.this, nextactivity.class);
intent.putExtra("imagename",youreditText.getText().toString());
startActivity(intent);
In next activity take this image name from bundle and use following code to set image in your imageview dynamically:
ImageView image = (ImageView)findViewById(R.id.yourimageid);
int id = getResources().getIdentifier(imagename, "drawable", getPackageName());
image.setImageResource(id);
I am developing an application for Android.
My application contains ten buttons, to which I have set an onclicklistener() method.
The ten buttons contains the digits 0-9.
Now, if I click any two or three buttons among the ten buttons, the corresponding digits must be entered into edit text and it must be shown in the edittext box.
I am able to display the single digit if I click on any of the buttons, but if I click on another button, then the previous value disappears and the new value is shown.
But what I want is this: no matter how many buttons I click, that no. of digits will appear in the edittext box.
Please can anyone explain to me the code, or give me a hint so that it can be made in a simpler way.
Using Shared Preferences:
I think, you may used Shared Preferences when you button was click, get value from Edittext and put on shared preferences. After click next button get that shared preferences value. You may used each button click put on value shared preferences.
Go to this problem, which is help you to solve: >> SharedPreference problem in android
Using Intent:
May be used this code on button click event:
Bundle extras = getIntent().getExtras();
String value1 = extras.getString("Value1");
String value2 = extras.getString("Value2");
if (value1 != null && value2 != null) {
EditText text1 = (EditText) findViewById(R.id.EditText01);
EditText text2 = (EditText) findViewById(R.id.EditText02);
text1.setText(value1);
text2.setText(value2);
}

You are using editText.setText("");
Instead you must use editText.append();
You can take a public static String variable and concat the new value to previous and set it to EditText
Use below code
public class AsActivity extends Activity {
/** Called when the activity is first created. */
Button b1,b2,b3;
EditText et;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
b1=(Button)findViewById(R.id.button1);
b2=(Button)findViewById(R.id.button2);
b3=(Button)findViewById(R.id.button3);
et=(EditText)findViewById(R.id.editText1);
}
public void onclick(View v){
switch(v.getId()){
case R.id.button1:
et.append("1");
break;
case R.id.button2:
et.append("2");
break;
case R.id.button3:
et.append("3");
break;
}
}
}
here i have use property of button you can use switch statement as shown above in ur onclicklistener
In all 0-9 buttons onclick event you can write following code.
editText.setText((editText.getText().toString) +""+ nevText);
When you click on button then above code set newText with previous text in edittext box.
You should use the EditText append() method which appends data to the EditText.
So each time a new button is clicked just use :
myEdtiText.append(str);
