使顶部和Android的软键盘的设备之间的编辑文本出现 [英] make an edit text appear between the top and the soft keyboard of the device in android
问题描述
我有很多ViewsStubs滚动型布局，这些意见存根充气（显示）取决于用户的行为像.....回答问题1，使第二问题和答案字段（EDITTEXT）出现
I have a scrollview layout with many ViewsStubs and these views stubs are inflated (displayed) depending on the user actions like.....answering the 1st questions makes the 2nd question and answer field(editText) appear
我的问题是回答第一个问题，点击提交后，接下来的问题是由可见的，但答案字段软键盘下隐藏......用户无法看到他是打字。
my problem is after answering the 1st question and clicking submit, the next question is made visible but the answer field is hidden under the soft keyboard...user cannot see what he is typing.
我想是任何新显示EDITTEXT /微调/复选框必须出现在屏幕上（动态滚动到这些意见）的顶部。
what i want is any newly displayed editText/spinner/checkbox must appear at the top of the screen (dynamically scroll to these views).
如何实现这一目标？
推荐答案
把我的code为例适合你，你可以这样做如下：
制作的 XML 为：
Take my code as example for you, You can do something like following: Make XML as:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:id="@+id/scrlv"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#123789" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#1188ff" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@+id/headerlayout"
android:background="#456789" >
<EditText
android:id="@+id/etemail"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="40dp"
android:hint="Text 1"
android:maxLines="3" />
<EditText
android:id="@+id/etpassword"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/etemail"
android:layout_alignRight="@+id/etemail"
android:layout_below="@+id/etemail"
android:hint="Text 2"
android:inputType="textPassword"
android:maxLines="3" />
<EditText
android:id="@+id/etusername"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/etemail"
android:layout_alignRight="@+id/etemail"
android:layout_below="@+id/etpassword"
android:hint="Text 3"
android:maxLines="3" />
<EditText
android:id="@+id/etphone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/etemail"
android:layout_alignRight="@+id/etemail"
android:layout_below="@+id/etusername"
android:hint="Text 4"
android:inputType="text"
android:maxLines="5" />
<CheckBox
android:id="@+id/chkterms"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/etemail"
android:layout_alignRight="@+id/etemail"
android:layout_below="@+id/etphone"
android:layout_marginTop="10dp"
android:text="Conditions Aplly"
android:textColor="@android:color/black" />
<Button
android:id="@+id/btnlogin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/chkterms"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp"
android:text="Login" />
</RelativeLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
然后code：
[1]获取设备的屏幕分辨率：高度，宽度
[1] Get device's screen resolution: Height, Width
[2]把你的EditText的onFocusChange
[2] Take onFocusChange of your EditText
[3]，如果您获得的EditText然后集中
[3] In that, if your EditText gets focus then
[4]把那EditText上的底部，如果底部是大于（ScreenHeight / 3），那么
[4] Get that EditText's Bottom, if that Bottom is greater then (ScreenHeight / 3) then
[5]滚动Your_ScrollView至（左，（ScreenHeight / 3））;
[5] Scroll Your_ScrollView to (left, (ScreenHeight/3));
public class MainActivity extends Activity implements OnClickListener{
private EditText etEmail, etPassword, etUserName, etPhoneNo;
private CheckBox chkTerms;
private Button btnLogin;
ScrollView scrlv;
int sw, sh, left, bottom;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scrlv = (ScrollView) findViewById(R.id.scrlv);
etEmail = (EditText) findViewById(R.id.etemail);
etPassword = (EditText) findViewById(R.id.etpassword);
etUserName = (EditText) findViewById(R.id.etusername);
etPhoneNo = (EditText) findViewById(R.id.etphone);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
sw = dm.widthPixels;
sh = dm.heightPixels;
System.out.println("Screen Width = " + sw);
System.out.println("Screen Height = " + sh);
chkTerms = (CheckBox) findViewById(R.id.chkterms);
btnLogin = (Button) findViewById(R.id.btnlogin);
btnLogin.setOnClickListener(this);
etUserName.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(etUserName.hasFocus()) {
left = etUserName.getLeft();
bottom = etUserName.getTop();
if (bottom > sh / 3) {
System.out.println("Umn Left :: " + left);
System.out.println("Umn Bottom :: " + bottom);
scrlv.scrollTo(left, (sh/3));
left = etUserName.getLeft();
bottom = etUserName.getTop();
System.out.println("Umn Left :: " + left);
System.out.println("Unm Bottom :: " + bottom);
}
}
}
});
etPhoneNo.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(etPhoneNo.hasFocus()) {
left = etPhoneNo.getLeft();
bottom = etPhoneNo.getTop();
if (bottom > sh / 3) {
System.out.println("Phno Left :: " + left);
System.out.println("Phno Bottom :: " + bottom);
scrlv.scrollTo(0, (sh/3));
left = etPhoneNo.getLeft();
bottom = etPhoneNo.getTop();
System.out.println("Phno Left :: " + left);
System.out.println("Phno Bottom :: " + bottom);
}
}
}
});
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
