android add checkbox dynamically

Question

The following are my layout xmls. Now we are have a limited number (seven) of check boxes in the layout (listitem.xml). And we are adding it in a linear layout.

main.xml

    <!-- </RelativeLayout> -->

</LinearLayout>

But as per the new requirement we need to add the check boxes dynamically. Like need to fetch the options from the API call and convert it as check boxes in the view. I spent lots of time in it. Can someone suggest a method to solve this.

Our layout should be like this. In a list view we are displaying employee details and for each employee record the qualification should be loaded from the API call or database.

      [Reviewer Name (Editable)]       
               Employee Lest           
---------------------------------------
Employee1                    [Click Me]

Male (0)          Female ( )
Salary : [5999 (editable)]
Qualification

[ ]BSc
[ ]Matriculation
[ ]Other
[Submit Button]
---------------------------------------
Employee2                    [Click Me]

Answer 1

Add CheckBox Dynamically

LinearLayout my_layout = (LinearLayout)findViewById(R.id.my_layout);
// Add Checkbox Dynamically
CheckBox checkBox = new CheckBox(mContext);
checkBox.setText(ETnewcheckbox.getText().toString()+""); 
checkBox.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        String msg = "You have " + (isChecked ? "checked" : "unchecked") + " this Check it Checkbox.";
        Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
    } 
}); 

// Add Checkbox to LinearLayout 
if (my_layout != null) { 
    my_layout.addView(checkBox); 
} 

Answer 2

Try this.

 LinearLayout lLayout = (LinearLayout)findViewById(R.id.yourMainLayout);
 CheckBox checkBox = new CheckBox(this);   // Here you will create CheckBox as many number of Checkbox you want.

 lLayout.addView(checkBox); // Here you have to add this CheckBox to your layout.

Good Luck.

Answer 3

LinearLayout featuresTable = (LinearLayout) findViewById(R.id.failure_reasonslist);
// use loop 
CheckBox feature1 = new CheckBox(this);
featuresTable.addView(feature1 );
