I'm trying to show a simple prompt dialog fragment programatically. I've extended SherlockFragmentActivity, and coded a custom SherlockDialogFragment implementation in it.
(I'm using ActionbarSherlock library, but I think the problem doesn't have to do with it, and would also be observed using regular ActionBar and Fragments).
This is the overriden oncreateDialog method inside the custom FragmentActivity class:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
//Skipped section. Setting positive, negative buttons, title, message on builder.
efPsw = new EditText(getActivity());
// Hacky margin stuff (yeah, I know it's dirty)
DisplayMetrics displaymetrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int smallestSide = Math.min(displaymetrics.heightPixels, displaymetrics.widthPixels);
int margin = (int)(0.5 * ((double) smallestSide));
efPsw.setTransformationMethod(PasswordTransformationMethod.getInstance());
FrameLayout fl = new FrameLayout(getActivity());
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(margin, 0, margin, 0);
fl.addView(efPsw, layoutParams);
builder.setView(fl);
return builder.create();
}
When I show the fragment, the inner framelayout is not shown (looks like an invisible rectangle that grows in height with each typed character). I'm not sure what am I doing wrong here, but certainly something must be wrong, since if I put the edittext in setView everything works fine (but without margin).
Thanks in advance.
it looks like you are making the margin half the smallest side, which in portrait mode would make your margin the entire screen. i would start by reducing the margin.
you can apply the margins directly to the EditText using the setLayoutParams() method. That would eliminate the FrameLayout.

i have created a custom view
CameraView extends View{
.....
}
in OnCreate methode i have define as
cameraView = new CameraView(this);
LayoutParams layoutParamsCamera
= new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT);
this.addContentView(cameraView, layoutParamsCamera);
but this use full screen i need to use as
marginBootom= 20dp or paddingBoototm= 20dp
so how i can add this parameter to LayoutParams??
i need help
& sorry for my bad English
Use MarginLayoutParams instead of whatever flavor of LayoutParams you're now using to set view layout margins programmatically.
I want to achieve the following design: A dialog with custom layout, created programatically. It will contain an EditText and a Button. I want the soft keyboard to pop up when the dialog appears, and I want the dialog to fill the screen horizontally and to be placed right above the keyboard.
Here is what I've done right now:
final AlertDialog obsDialog = new AlertDialog.Builder(ProdutoDetalheActivity.this).create();
final View obsLayout = View.inflate(getApplicationContext(), R.layout.observation_layout, null);
Button obsButton = (Button) obsLayout.findViewById(R.id.observation_button);
obsEdit = (EditText) obsLayout.findViewById(R.id.observation_edit);
obsButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.setText(String.valueOf(obsEdit.getText()));
obsDialog.dismiss();
}
});
obsDialog.setView(obsLayout);
obsDialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
obsDialog.show();
obsEdit.requestFocus();
But this doesn't makes the dialog full width, nor calls the soft keyboard. And I still wonder how can I align the dialog with the keyboard.
I've tried these answers with no success.
Thanks in advance for any help!
[EDIT] I've brought the keyboard up by using the following code:
obsDialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
obsDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
[EDIT] Below is a printscreen of the design I want to achieve:
As far as I know, you have to adjust the dialog size/position in the code if you do not want the default size/position.
In you case specifically, you can fist declare adjustResize for the activity's windowSoftInputMode in the AndroidManifest.xml.
After that, you can set your dialog gravity at bottom and set the width in the onStart of the dialog fragment:
...
getDialog().getWindow().setLayout(mWidth, mHeight);
WindowManager.LayoutParams lp = getDialog().getWindow().getAttributes();
lp.gravity = Gravity.BOTTOM;
lp.x = 0; lp.y = 0;
getDialog().getWindow().setAttributes(lp);
...
the mWidth and mHeight are initialized in onCreate, but I think you can do it in the onStart as well. To get the width, I used below code:
Point size = new Point();
WindowManager wm = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
display.getSize(size);
mWidth = size.x;
Hope this can meet your requirement. I used this to create a similar dialog, but I do not have a edit in the dialog. And I need it to be at the bottom of the screen.
I want to implement a help overlay for my app.
It should look like this: How do I create a help overlay like you see in a few Android apps and ICS?
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.setContentView(R.layout.coach_mark);
dialog.setCanceledOnTouchOutside(true);
//for dismissing anywhere you touch
View masterView = dialog.findViewById(R.id.coach_mark_master_view);
masterView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
dialog.dismiss();
}
});
dialog.show();
This works very well. The RelativeLayout of coach_mark.xml is displayed over my existing layout which was set via setContentView().
Now I want to align the views of coach_mark.xml near the according views of the existing layout, in order to react dynammically to the resolution and screen size. This is what I have tried:
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.BELOW,R.id.view_of_main_layout);
view_of_the_overlay.setLayoutParams(lp);
But the view is displayed just in the middle of the screen.
The only thing I could archieve is to align the view to bottom of screen, but that is not what I want to do.
Thanks for your help.
You can use PopupWindow :
PopupWindow popup=new PopupWindow(this);
popup.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
popup.setWindowLayoutMode(FrameLayout.LayoutParams.WRAP_CONTENT,FrameLayout.LayoutParams.WRAP_CONTENT);
popup.setContentView(R.layout.coach_mark);
View view=findById(R.id.view_of_main_layout);
int[] viewLocation=new int[2];
view.getLocationInWindow(viewLocation)
popup.showAtLocation(view, Gravity.TOP|Gravity.LEFT, viewLocation[0],viewLocation[1]);
you can also adjust to popup location with the last two variables which are the X and Y offest. Their values can also be negative.
I want to create a relative Layout dynamically through code with 2 Textviews one below the other.How to implement android:layout_below property through code in Android.
can anyone help me in sorting out this issue.
Thanks in Advance,
final TextView upperTxt = (...)
upperTxt.setId(12345);
final TextView lowerTxt = (...);
final RelativeLayout.LayoutParams params = RelativeLayout.LayoutParams(this, null);
params.addRule(RelativeLayout.BELOW, 12345);
lowerTxt.setLayoutParams(params);
Here is my solution for my special Problem.
In case the username wouldn't be found in the db i had to create a RelativeLayout that looks like the xml-generated one.
// text view appears on top of the edit text
enterNameRequest = new TextView(mainActivity.getApplicationContext());
// fill the view with a string from strings.xml
enterNameRequest.setText(mainActivity.getResources().getString(R.string.enterNameRequest));
// edit text appears below text view and above button
enterName = new EditText(mainActivity.getApplicationContext());
enterName.setId(667);
// button appears at the bottom of the relative layout
saveUserName = new Button(mainActivity.getApplicationContext());
saveUserName.setText(mainActivity.getResources().getString(R.string.useUserName));
saveUserName.setId(666);
// generate the relative layout
RelativeLayout layout = new RelativeLayout(mainActivity.getApplicationContext());
layout.setId(668);
// set a background graphic by its id
layout.setBackgroundDrawable(mainActivity.getApplicationContext().getResources().getDrawable(R.drawable.background_head_neutral));
// runtime told me that i MUST use width and height parameters!
LayoutParams params2 = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
params2.addRule(RelativeLayout.ABOVE, 666);
enterName.setLayoutParams(params2);
LayoutParams params3 = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
params3.addRule(RelativeLayout.ABOVE, 667);
enterNameRequest.setLayoutParams(params3);
LayoutParams params4 = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
params4.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 668);
saveUserName.setLayoutParams(params4);
// add views
layout.addView(enterNameRequest);
layout.addView(enterName);
layout.addView(saveUserName);
/* todo: set button action */
mainActivity.setContentView(layout);
What i found out additionally:
It is not so good to manipulate the layout manually from within java!
You should better use a new Activity and set a new layout in it.
This way, the application-code is readable a lot better!
I even tried to set several layouts (not manually, but wit setContentView) in one activity, and it turned out that i didn't know where what was accessing what else... Also, i had a great problem in adding onClickListeners... so you better use -- android:onClick="myButtonMethod" -- in your button tag in the xml and have a method in your according activity, which uses the layout, like this:
public void myButtonMethod(View v){
// do stuff
}
This improves performance because you are not using additional Listeners - but you use the already available Listener that is bound to your activity in every case.
u can try this
LinearLayout.LayoutParams leftMarginParams = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);``
leftMarginParams.leftMargin = 50;
Button btn1 = new Button(this);
btn1.setText("Button1");
linLayout.addView(btn1, leftMarginParams)
I have a form with several Views on it, the last one is a Spinner that is bound to an adapter to get it's data from a Web Server via a POST request, at the end I append an additional entry for "Other...". If this option is selected on the spinner, a new EditText View at the bottom where the user enters a custom value, I've managed to get the EditText View to show on the screen, but it's positioned at the very top, over my other Views and I can't seem to find the way to make it appear at the bottom, below the Spinner as I want it to, here is the code I have so far:
EditText suggestCarrierField = new EditText(getBaseContext());
suggestCarrierField.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
suggestCarrierField.setHint("Suggest your carrier");
((AbsoluteLayout) findViewById(R.id.createAccountView)).addView(suggestCarrierField);
((AbsoluteLayout) findViewById(R.id.createAccountView)).invalidate();
Using an AbsoluteLayout, you need to use AbsoluteLayout.LayoutParams, rather than ViewGroup.LayoutParams.
int width = 100, height = 25, x = 0, y = 200;
AbsoluteLayout.LayoutParams lp = new AbsoluteLayout.LayoutParams(width, height, x, y);
suggestCarrierField.setLayoutParams(lp);
Having said that, I strongly urge you to consider implementing this with a RelativeLayout (or LinearLayout) instead... AbsoluteLayout is deprecated, and for very good reason. There are so many different Android devices with different sized screens now, AbsoluteLayout just won't work across them all.
When setting the LayoutParams for suggestCarrierField, don't use ViewGroup but instead use AbsoluteLayout.LayoutParams. It has a constructor which takes a height, width AND x and y coordinates. See the AbsoluteLayout.LayoutParams doc . Here is a quick app I whipped which demos this:
public class AbsoluteLayoutTest extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AbsoluteLayout as = new AbsoluteLayout(this);
TextView tvTop = new TextView(this);
tvTop.setText("top");
tvTop.setLayoutParams(new AbsoluteLayout.LayoutParams(AbsoluteLayout.LayoutParams.FILL_PARENT, AbsoluteLayout.LayoutParams.WRAP_CONTENT, 0, 0));
TextView tvMid = new TextView(this);
tvMid.setText("middle");
tvMid.setLayoutParams(new AbsoluteLayout.LayoutParams(AbsoluteLayout.LayoutParams.FILL_PARENT, AbsoluteLayout.LayoutParams.WRAP_CONTENT, 0, 80));
TextView tvBot = new TextView(this);
tvBot.setText("bottom");
tvBot.setLayoutParams(new AbsoluteLayout.LayoutParams(AbsoluteLayout.LayoutParams.FILL_PARENT, AbsoluteLayout.LayoutParams.WRAP_CONTENT, 0, 180));
as.addView(tvTop);
as.addView(tvMid);
as.addView(tvBot);
setContentView(as);
}
}
This will result in three text views. One at the top (y-coord = 0), one in the middle (y-coord = 80) and one at the bottom (y-coord = 180).
