我有以下布局(实际上是空的):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/set_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:contentDescription="content desc"
android:orientation="vertical" >
<TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, I am a TextView" />
</LinearLayout>
Activity类包含以下内容:
public class TestActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
}
}
当我在我的移动设备上运行这个，我得到以下错误:
SpannableStringBuilder
SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
我已经尝试了这个与没有TextView和错误仍然存在，我一定是做了根本性的错误为这样一个基本的布局，导致这一点。
有人有什么想法吗，我怎么才能让这个加载没有错误?
这对我很管用……在每个设备上
<EditText
android:maxLines="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="15sp"
android:layout_centerVertical="true"
android:textColor="#000"
android:id="@+id/input_search"
android:background="@null"
android:inputType="text"
android:hint="Enter Address, City or Zip Code"
android:imeOptions="actionSearch"
/>
在Java代码中:
mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
if(actionId == EditorInfo.IME_ACTION_SEARCH
|| actionId == EditorInfo.IME_ACTION_DONE
|| keyEvent.getAction() == KeyEvent.ACTION_DOWN
|| keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){
//execute our method for searching
}
return false;
}
});
