在我的应用程序中，我从 JSON 获取文本内容，并将该内容显示到文本视图中。但是，问题是文本看起来不完整，也没有格式化。我使用http://jsonformatter.curiousconcept.com/检查了我的 JSON，它显示 JSON 是有效的。我已经在日志上打印了我收到的内容，它是完整的。甚至，在将其设置为 textview 并再次从中恢复后，我得到了完整的数据。但是，它没有显示完整的文本。
我没有找到问题所在。文本视图在滚动视图内。
下面是我的代码： 基本活动
public class TIEBaseActivity extends MapActivity
{
//private ProgressDialog dialog;
public AlertDialog _alertDialog;

LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(resourceID, null);
_manager.addView(view);
}
public void loadDefaultForm()
{
form=new LinearLayout(this);
form.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
form.setOrientation(LinearLayout.VERTICAL);
form.setGravity(Gravity.CENTER);
_manager.addView(form);

startActivity(intent);

public void setHeaderTitle(String title) {
if (_headerBar!=null) {
_headerBar.setTitle(title);
}
}
public Handler progressCloseHandler = new Handler() {

String mMailMessage = null;
mMailMessage = "Hi,\n I found this great Application. This application customize for Overseas Indian Events.";
mMailMessage += "\n";
mMailMessage += "Go to: https://market.android.com/details?id=com.dzo.oie";
mMailMessage += ",\n Please visit: http://www.dotzoo.net to see more about Dotzoo Inc.";
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/*");
emailIntent.putExtra(Intent.EXTRA_SUBJECT, ""+mMailSubject);
emailIntent.putExtra(Intent.EXTRA_TEXT, mMailMessage);
startActivity(Intent.createChooser(emailIntent, "Share via..."));

}
BaseActivity 的布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:background="@color/white"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="@+id/baseLayout">
<com.dzo.tie.ui.HeaderBar

android:layout_height="50dp"/>
<ScrollView
android:scrollbars="vertical"

我在我的活动类中扩展了这个基本活动：
我的活动
public class TIEInfo extends TIEBaseActivity
{
TextView txtTieInfo;
String contents;
private String infoUrl = "http://www.tradeineu.com/tie_app/aboutTie.php";
protected void onCreate(Bundle savedInstanceState)
{
super.createDefaultView(savedInstanceState);
_headerBar.view.setVisibility(View.VISIBLE);
super.setHeaderTitle("Info");
init();
new TIEInfoAsyncTask(getParent(), infoUrl, txtTieInfo).execute();
}//onCreate
public void init()
{
loadFormFromResource(R.layout.tieinfo);
txtTieInfo = (TextView)findViewById(R.id.txtTieInfo);
}//init
}//TIEInfo
