In your java class, set the "<code>EditText</code>" Type to "<code>TextView</code>". Because you have declared a <code>TextView</code> in the <code>layout.xml</code> file

blocks|key|1197691|text|代码应该是这样的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1197692|TextView+text+=+(TextView)+findViewById(R.id.this_is_the_id_of_textview);

The code should instead be something like this:

To settext in any of in activity than use this below code...
 Follow these step one by one:

1.Declare

</code></pre>

2.Bind this 

<pre><code> event_post = (TextView) findViewById(R.id.text_post);
</code></pre>

3.SetText in 

<pre><code> event_post.setText(event_post_count);
</code></pre>

blocks|key|983325|text|试着这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|983326|TextView+text=(TextView)findViewById(R.id.textviewID);
text.setText("Text");|code-block|syntax|javascript|983327|而不是这样：|983328|text+=+(EditText)+findViewById(R.id.this_is_the_id_of_textview);

Try Like this :

Instead of this:

<pre><code>text = (EditText) findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");
</code></pre>

blocks|key|1197839|text|或者你可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1197840|((TextView)findViewById(R.id.this_is_the_id_of_textview)).setText("Test");|code-block|syntax|javascript|1197841|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Or you can do this way :

<pre><code>((TextView)findViewById(R.id.this_is_the_id_of_textview)).setText("Test");

blocks|key|1197945|text|我也有类似的问题，但是当我尝试设置文本时，我的程序会崩溃。我试图从扩展AsyncTask的类中设置文本值，这就是导致问题的原因。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1197946|为了解决这个问题，我将setText移到了onPostExecute方法中|1197947|protected+void+onPostExecute(Void+result)+{

I was having a similar problem, however my program would crash when I tried to set the text. I was attempting to set the text value from within a class that extends AsyncTask, and that was what was causing the problem. 

To resolve it, I moved my setText to the onPostExecute method

<pre><code>protected void onPostExecute(Void result) {
 super.onPostExecute(result);

 TextView text = (TextView) findViewById(R.id.errorsToday);
 text.setText("new string value");
}
</code></pre>

blocks|key|1197794|text|在XML中，您使用的是Textview，但在Java+Code中，您使用的是EditText，而不是TextView。如果将其更改为TextView，则可以将文本设置为TextView对象。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1197795|text+=+(TextView)+findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");|code-block|syntax|javascript|1197796|希望它能起作用。|1197797|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

In your XML, you had used Textview, But in Java Code you had used EditText instead of TextView. If you change it into TextView you can set Text to to your TextView Object.

<pre><code>text = (TextView) findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");
</code></pre>

hope it will work.

blocks|key|983449|text|您将文本设置为一个字段，该字段在您的活动的另一个驻留在现金中的实例中呈现，例如当它是面向横向的时候。然后由于某种原因它被重新创建了。您需要以一种不寻常的方式设置文本，方法是将字符串保存到SharedPreferences，然后使用recreate()强制重新启动活动，比如mOutputText：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|983450|@Override

You set the text to a field that was rendered in another instance of your activity residing in cash,say when it was landscape oriented. Then it was recreated due to some reason. You need to set the text in an unusual way by saving the string to SharedPreferences and force relaunch the activity using recreate(), say for mOutputText:

<pre><code>@Override
protected void onResume() {
 super.onResume();
 String sLcl=mPreferences.getString("response","");
 if(!sLcl.isEmpty()){
 mOutputText.setText(sLcl);
 mPreferences.edit().putString("response","").commit();
 }
}

private void changeText() {
 mPreferences.edit().putString("response",responseText).commit();
 recreate();
}
@Override
protected void onActivityResult(
 int requestCode, int resultCode, Intent data) {
 super.onActivityResult(requestCode, resultCode, data);
 switch (requestCode) {
 case CAPTURE_MEDIA_RESULT_CODE:
 if (null == data || null == data.getData()) {
 showMessage("Sorry. You didn't save any video");
 } else {
 videoUri = data.getData();
 mProgress = new ProgressDialog(this);
 mProgress.setMessage("Uploading onYoutube ...");

 authorizeIt();// SAY YOU CALL THE changeText() at the end of this method
 }
 break;
 }
}

I'm having a problem with setting text to a TextView:

<pre><code>TextView android:editable = "true".
</code></pre>

In my .java it seems like that this should work:

<pre><code> text = (EditText) findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");
</code></pre>

But it doesn't. Can anyone tell me what's wrong here?

Why can't I set text to an Android TextView?

我在将文本设置为TextView时遇到问题：TextView android:editable = "true".在我的.java中，这看起来应该是可行的： text = (EditText) findViewById(R.id.this_is_the_id_of_textview);text.setText("TEST");但事实并非如此，有人能告诉我这里出了什么问题吗？
