我试图忽略回车键,但我不想使用onKeyDown()函数。
有一种方法可以在xml中执行此操作: 1. android:maxLines =“1” 2. android:lines =“1” 3. android:singleLine =“true”
我实际上想通过编码来完成最后一个。有谁知道怎么做?
for (int i=0; i<numClass; i++) {
temp_ll = new LinearLayout(this);
temp_ll.setOrientation(LinearLayout.HORIZONTAL);
temp1 = new EditText(this);
InputFilter[] FilterArray = new InputFilter[1];
FilterArray[0] = new InputFilter.LengthFilter(12);
temp1.setFilters(FilterArray); // set edit text length to max 12
temp1.setHint(" class name ");
temp1.setSingleLine(true);
temp_ll.addView(temp1);
frame.addView(temp_ll);
}
ll.addView(frame);

这是我试过的:
public class Next extends Activity{
LinearLayout lay;
LinearLayout temp_ll;
EditText temp1;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.next);
lay=(LinearLayout)findViewById(R.id.lay);
temp_ll = new LinearLayout(this);
temp_ll.setOrientation(LinearLayout.HORIZONTAL);
temp1 = new EditText(this);
InputFilter[] FilterArray = new InputFilter[1];
FilterArray[0] = new InputFilter.LengthFilter(12);
temp1.setFilters(FilterArray); // set edit text length to max 12
temp1.setHint(" class name ");
temp1.setSingleLine(true);
temp_ll.addView(temp1);
lay.addView(temp_ll);
}
}
Xml是:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/lay"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</LinearLayout>
</LinearLayout>

尝试使用setSingleLine
作为:
EditText editText=(EditText)findViewById(R.id.editv);
editText.setSingleLine(true);
