创建许多TextView并给它们提供ID之后，我试图用他们的信息打开一个活动。 我怎么做？

Question

So I can successfully create an android Text View using java and set it a value and an ID. But my problem is that after I create them and gave them values and id, I have no control over them. After clicking on them, I want the new page to have the data that was stored in that Text View.

Here is how I created and set value and ID to my Text Views:

                             textView = new TextView(SellActivity.this);

                            // put the data in the text view
                            textView.setText(data);


                            // give it an id
                            textView.setId(Integer.parseInt(getStrID));


                            //place it nicely under one another
                            textView.setPadding(0, 50, 0, 0);

                            // if clicked any of the textviews, open the offer page
                            textView.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View view) {
                                    //setGetStrID(getStrID);
                                    Intent intent = new Intent(SellActivity.this, OfferActivity.class);
                                    startActivity(intent);
                                }
                            });

                            // add the text view to our layout
                            linearLayout.addView(textView);

Answer 1

You can put the data in the intent when you are opening a new activity

textView.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View view) {
                                //setGetStrID(getStrID);
                                Intent intent = new Intent(SellActivity.this, OfferActivity.class);
                                intent.putExtra("mydata", textView.getText());
                                startActivity(intent);
                            }
                        });

In the oncreate of OfferActivity receive this data as string

String mydata = intent.getStringExtra("mydata");

Answer 2

You just have to pass the data to the new intent,

textView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
             Intent intent = new Intent(SellActivity.this, OfferActivity.class);
             intent.putExtra("TextViewContent", textView.getText());
             startActivity(intent);
        }
});

Then in onCreate function of OfferActivity.java ,

String s = getIntent().getStringExtra("TextViewContent");

Now the string s will contain the value of your textView.
