Inflate textviews with differents values in a Layout

Question

I already looked for some answer on the internet but i didn't find so i'm asking for your help I want to add a TextView everytime i click on a button but with a different value. For exemple, first click adds a TextView with the number 1, second click adds a TextView with the number 2. My app crashs everytime i call the method.

Here the code

public class Activity_Planification_Actu extends AppCompatActivity {

    LinearLayout mparent;
    LayoutInflater layoutInflater;
    int i = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.page_planification);
        mparent = findViewById(R.id.Layout1);
        layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
    }



    public void boutonTest(View v) {

        View myview = layoutInflater.inflate(R.layout.semaine_planif, null, false);
        TextView tv = (TextView) myview.findViewById(R.id.case_semaine);
        tv.setText(i);
        i++;
        mparent.addView(myview);

    }

}

To be more precised i want right to the textview another textview but with a different text

Answer 1

Your problem in:

tv.setText(i);

You call to setText with int argument and Android think that you pass String's resource id like tv.setText(R.string.some_text) and cant find resource which id is equals to i i.e. 0 that's why this crash happend .

You should use:

tv.setText(String.valueOf(i)); 
//or
tv.setText("" + i); 

Answer 2

provide Logcat

or

try this can do with loop

LinearLayout my_ll = (LinearLayout) findViewById(R.id.Layout1);
        for(int i=0;i<your_number_of_textviews;i++)
        {
            TextView text = new TextView(this);
            text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            text.setText("text"+i);
            my_ll.addView(text);
        }

every button click logic

LinearLayout my_ll = (LinearLayout) findViewById(R.id.Layout1);
int clickcount=0; //set as global 
yourbutton.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        clickcount=clickcount+1;
        if(clickcount==0)
        {
            //check how many times clicked and so on
            //here, you can add textview without loop 
            TextView text = new TextView(this);
            text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            text.setText("text"+clickcount);
            my_ll.addView(text);

        
    }
});
