Error setting text to a textView from strings.xml via java code

Question

I just want to set a text in a textView from strings.xml using java code but I just can't, eclipse gives me this error: "textView1 cannot be resolved" and "textView2 cannot be resolved".

Here is mi activity:

package com.example.activity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ImageView;

public class Descripcion extends Activity{

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.descripcion);

    Intent i = getIntent();

    int position = i.getExtras().getInt("id");
    ImageAdapter imageAdapter = new ImageAdapter(this);

    switch (position){
    case 0:

    ImageView imageView0 = (ImageView) findViewById(R.id.full_image_view);
    imageView0.setImageResource(imageAdapter.mThumbIds[position]);

    textView1.setText(this,getString(R.string.case0));
    textView2.setText(this,getString(R.string.case0b));

    break;

    case 1:

    ImageView imageView1 = (ImageView) findViewById(R.id.full_image_view);
    imageView1.setImageResource(imageAdapter.mThumbIds[position]);

    textView1.setText(this,getString(R.string.case1));
    textView2.setText(this,getString(R.string.case0b));

    break;  
    }
}
}

I've beeing looking for a solution for about 3 hours but I can't fid it.

I can't see where you are declaring your TextView's, such as:

TextView textView1 = (TextView)findViewById(R.id.textView1);

Thanks a lot! I'm just doing my first app for android, in objective-c you have to define labels and buttons in other file, I forgot that in java it's diferent =D

No worries, we've all been there. I went from PHP to Java, talk about a learning curve :)

1) You didn't define TextView

2) You didn't do findViewById to get corresponding TextView

How to do that?

Your code itself has clues on how to do that, example:

ImageView imageView1 = (ImageView) findViewById(R.id.full_image_view);

Here you defined ImageView and pointed it to R.id.full_image_view defined in layout.xml

like this you need to get TextView, example:

TextView textView1 = (TextView)findViewById(R.id.textView1);

I've define my TextView but now I have this error: The method setText(CharSequence, TextView.BufferType) in the type TextView is not applicable for the arguments (activity, String) activity.java /aplicacion/src/com/example/memepedia line 31 Java Problem

Why this as first parameter? shouldn't it be just setText(getString(R.string.case1))?

You forgot to define the variables textView1 and textView2. Besides that you need to obtain a reference to them using findViewById. Weird part is that you did this for imageView1 and forgot to do it for the TextViews.

Add the following piece of code below etContentView(R.layout.descripcion):

TextView textView1 = (TextView) findViewById(<<-- the id of textView1 -->>); TextView textView1 = (TextView) findViewById(<<-- the id of textView2 -->>);

That's because textView1 and textView2 aren't defined....

You see what you do with the ImageView?

ImageView imageView0 = (ImageView) findViewById(R.id.full_image_view);

You have to apply the same concept to the text views.

TextView textView1 = (TextView) findViewById(R.id.id_of_text_view_1);
TextView textView2 = (TextView) findViewById(R.id.id_of_text_view_2);

Then you can perform operations on that text view, such as setting the text!

define your textviews as you did your imageview.

you can use

TextView textView1 = (TextView)findViewById(R.id.textView1);
TextView textView2 = (TextView)findViewById(R.id.textView2);

where

R.id.textView1

is the id of your textview1 in your xml layout

R.id.textVie2

is the id of your textview2 in your xml layout
