I have this code, but the textview are all without Margin right and i don't know why.
I add some lines of onCreate for declaration.
And the functions about the creation of the textview.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLayout = (LinearLayout) findViewById(R.id.linearlayout);
mEditText = (EditText) findViewById(R.id.input_materia);
mButton = (Button) findViewById(R.id.add_materia);
mButton.setOnClickListener(onClick());
TextView textView = new TextView(this);
textView.setText("New text");
/*
* add textview from editext
*/
private OnClickListener onClick() {
return new OnClickListener() {
#Override
public void onClick(View v) {
mLayout.addView(createNewTextView(mEditText.getText().toString()));
}
};
}
private TextView createNewTextView(String text) {
final LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
lparams.setMargins(0, 0, 30, 0);
final TextView textView = new TextView(this);
textView.setLayoutParams(lparams);
textView.setText(text);
textView.setGravity(Gravity.CENTER);
return textView;
}
some helps?
Have you tried referencing Relative Layout Params or Linear Layout Params depending on what is set in your XML?
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);

I am trying to set padding to my linear layouts so that when I press 'create row' they have a gap between them each.
I tried adding marginTop and marginBottom to my LinearLayout but when I run the code, the layout is still spawn in together. not with a gap from the margin I set.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="#+id/verticalLayout"
android:layout_below="#id/button"
android:background="#color/colorPrimaryDark"
android:layout_marginTop="50dp"
>
(the above image shows 3 linear layouts I added by pressing create row)
Edit: I tried adding a marginRight to it, just to see if anything worked on it, and it did.
public class MainActivity extends AppCompatActivity {
LinearLayout verticallayout,horizontalLayout; //got
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
verticallayout = findViewById(R.id.verticalLayout); //got
}
public void createRow(View view){
createRow(); //got
}
private void createRow() { //got
horizontalLayout = new LinearLayout(this);
LinearLayout.LayoutParams horizontalParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalParams.setMargins(15, 5, 15, 5); // LEFT, TOP, RIGHT, BOTTOM
horizontalLayout.setLayoutParams(horizontalParams);
createSpinner();
createCheckbox();
createEditText();
verticallayout.addView(horizontalLayout, horizontalParams);
}
private void createEditText() {
EditText editText = new EditText(this);
LinearLayout.LayoutParams editParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
editParams.setMargins(10, 10, 10, 10);
editText.setLayoutParams(editParams);
horizontalLayout.addView(editText);
}
private void createCheckbox() { //done
CheckBox checkBox = new CheckBox(this);
LinearLayout.LayoutParams checkParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
checkParams.setMargins(10, 10, 10, 10);
checkParams.gravity = Gravity.LEFT;
checkBox.setLayoutParams(checkParams);
horizontalLayout.addView(checkBox);
}
private void createSpinner() {
Spinner spinner = new Spinner(this);
//ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item, spinnerArray);
//spinner.setAdapter(spinnerArrayAdapter);
LinearLayout.LayoutParams spinnerParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
spinnerParams.setMargins(10, 10, 10, 10);
spinnerParams.gravity = Gravity.LEFT;
spinner.setLayoutParams(spinnerParams);
horizontalLayout.addView(spinner);
}
}
Try this one code
private void createRow() { //got
horizontalLayout = new LinearLayout(this);
LinearLayout.LayoutParams horizontalParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalParams.setMargins(15, 5, 15, 5); // LEFT, TOP, RIGHT, BOTTOM
horizontalLayout.setLayoutParams(horizontalParams);
horizontalLayout.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.colorPrimaryDark));
createSpinner();
createCheckbox();
createEditText();
verticallayout.addView(horizontalLayout, horizontalParams);
}
hope so it will be useful for you. :)
Add margin to horizontal layout not in Vertical layout. check following code:
private void createRow() {
horizontalLayout = new LinearLayout(this);
LinearLayout.LayoutParams horizontalParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
horizontalParams.topMargin = 20; //add margin here.
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalLayout.setLayoutParams(horizontalParams);
createSpinner();
createCheckbox();
createEditText();
verticallayout.addView(horizontalLayout);
}
I have a Class that used in it below code
this.guageBack= (AbsoluteLayout) findViewById(R.id.gaugeFrame);
AbsoluteLayout.LayoutParams params = new AbsoluteLayout.LayoutParams(this.needleWidth,this.needleHeight,this.needleX,this.needleY);
gaugeNeedle.setLayoutParams(params);
AbsoluteLayout deprecated so When I want to use RelativeLayout I have not replcement for
AbsoluteLayout.LayoutParams(this.needleWidth,this.needleHeight,this.needleX,this.needleY);
Because it accept two args like below
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(needleWidth, needleHeight);
What should I do?
Just add this code instead of yours
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(needleWidth, needleHeight);
params.topMargin = needleY;
params.leftMargin = needleX;
Do it like this
public class CodeLayout extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Creating a new RelativeLayout
RelativeLayout relativeLayout = new RelativeLayout(this);
// Defining the RelativeLayout layout parameters.
// In this case I want to fill its parent
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT);
// Creating a new TextView
TextView tv = new TextView(this);
tv.setText("Test");
// Defining the layout parameters of the TextView
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
// Setting the parameters on the TextView
tv.setLayoutParams(lp);
// Adding the TextView to the RelativeLayout as a child
relativeLayout.addView(tv);
// Setting the RelativeLayout as our content view
setContentView(relativeLayout, rlp);
}
}
try this code,
AbsoluteLayout absoluteLayout = //get absolute layout
Button button = new Button();
AbsoluteLayout.LayoutParms params = absoluteLayout.generateDefaultLayoutParams();
params.x = 100;
params.y = 100;
absoluteLayout.addView(button, params);
Sorry for my English. I have a dynamically created TextView and ImageView, they are added to the LinearLayout. But when I start to write a TextView that it changes its size and thus reduces the ImageView. The picture below is an example of how the size of the
final LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
row.setOrientation(LinearLayout.HORIZONTAL);
//params editTExt
android.widget.LinearLayout.LayoutParams paramsEtext = new android.widget.LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);
paramsEtext.gravity = Gravity.LEFT;
//params image View
LinearLayout.LayoutParams paramsImageView = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.25f);
paramsImageView.gravity = Gravity.CENTER_VERTICAL;
//create edit text
final EditText etext = new EditText(QuicklyCreateQwestions.this);
etext.setLayoutParams(paramsEtext);
//add et in ArrayList
et.add(etext);
//set text in textView
etext.setText(qwestions.get(i).toString());
row.addView(etext);
//add ImageView in edit text
final ImageView imV = new ImageView(this);
imV.setLayoutParams(paramsImageView);
imV.setImageResource(R.drawable.t_del_poll);
imV.setId(i);
//set button in layaut
row.addView(imV);
//action if button click
imV.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
row.removeView(etext);
row.removeView(imV);
}
});
//add editText and button in layaut
LinearLayoutTextQwestions.addView(row);
as shown in image i need to set text view LEFT OF RADIO GROUP and i did it using java code....so i don't know to set parameter for LAYOUT LEFT OF="" in java code.....how to solve it ..please guide me this way...
this is class file......
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.rate_me_up);
textViewShowTime = (TextView) findViewById(R.id.tvTimeCount);
layout = (RelativeLayout) findViewById(R.id.linear);
Button btnp = (Button) findViewById(R.id.buttonp);
btnp.setOnClickListener(this);
}
#Override
public void onClick(View v) {
RadioGroup radioGroup = new RadioGroup(Rate_me_up.this);
radioGroup.setOrientation(0);
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
if (mLastRadioGroup != null)
p.addRule(RelativeLayout.BELOW, mLastRadioGroup.getId());
radioGroup.setId(mRadioGroupId++);
mLastRadioGroup = radioGroup;
layout.addView(radioGroup, p);
RadioButton radioButtonView = new RadioButton(Rate_me_up.this);
radioButtonView.setText("radio1");
radioButtonView.setId(id++);
radioButtonView.setButtonDrawable(R.drawable.e404);
radioButtonView.setChecked(false);
radioGroup.addView(radioButtonView, p);
RadioButton radioButtonView2 = new RadioButton(Rate_me_up.this);
radioButtonView2.setText("radio2");
radioButtonView2.setId(id++);
radioButtonView2.setChecked(false);
radioGroup.addView(radioButtonView2, p);
RadioButton radioButtonView3 = new RadioButton(Rate_me_up.this);
radioButtonView3.setText("radio3");
radioButtonView3.setId(id++);
radioGroup.addView(radioButtonView3, p);
radioButtonView3.setChecked(false);
TextView txt = new TextView(Rate_me_up.this);
txt.setText("FOOD QUALITY!");
layout.addView(txt, p);
radioGroup.setOnCheckedChangeListener(this);
}
Alright you can do it by this way:
TextView txt = new TextView(Rate_me_up.this);
txt.setText("FOOD QUALITY!");
RelativeLayout.LayoutParams params=
new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.LEFT_OF,radiofroup.getId());
txt.setLayoutParams(params);
layout.addView(txt);
Hope I answered your question. :)
addRule Do something like this..
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)button.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.addRule(RelativeLayout.LEFT_OF, R.id.id_to_be_left_of);
button.setLayoutParams(params);
When I create Activity and set new RelativeLayout right in onCreate(), all works fine.
But I think it's more convenient to create a class MView that extends RelativeLayout and do all the settings there. And if I do this, Activity stays empty. What should I change in MView (or shall I need to use RelativeLayout without extension)?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
RelativeLayout mLayout = new RelativeLayout(this);//Change this to MView mLayout=new MView(this);
//I've been trying to move text from here...
TextView tv = new TextView(this);
tv.setText("TestText");
tv.setTextAppearance(this, android.R.attr.textAppearanceSmall);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
tv.setLayoutParams(lp);
mLayout.addView(tv);
//... to here to MView class that extends RelativeLayout
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
setContentView(mLayout, rlp);
}
So, code for MView constructor is:
public MView(Context context) {
super(context);
TextView tv = new TextView(context);
tv.setText("TestText");
tv.setTextAppearance(context, android.R.attr.textAppearanceLarge);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
tv.setLayoutParams(lp);
this.addView(tv);
}
And onCreate becomes this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MView mLayout = new MView(this);
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
setContentView(mLayout, rlp);
}
It was VERY simple. When I created MView, my implementation of onLayout was empty. Obviously, I had to write
super.onLayout(arg0, arg1, arg2, arg3, arg4);
And it worked fine. Thanks for helping :)
It is better to set layout parmas to direct view rather than when you add another layout.
In your case, set wrong add rules for text now.
Corrected code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
RelativeLayout mLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
mLayout.setLayoutParams(rlp);
TextView tv = new TextView(this);
tv.setText("TestText");
tv.setTextAppearance(this, android.R.attr.textAppearanceSmall);
RelativeLayout.LayoutParams rlt = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
rlt.addRule(RelativeLayout.CENTER_IN_PARENT);
tv.setLayoutParams(rlt);
mLayout.addView(tv);
setContentView(mLayout);
}
