我有一个RelativeLayout,其EditText下面有一个Button.理想情况下,当用户单击EditText并填充多行文本时,RelativeLayout也会随着行的增加而扩展.但是,我现在的行为是,在EditText的第一行被填充之后,键盘开始覆盖它下面的Button,在EditText中的3-4行文本之后,Button被移到键盘下方.是否有任何方法可以让我在键入文本时,整个布局的大小增加,以便按钮保持在键盘上方?这是我的代码:
AndroidManifest.xml中:
<activity
android:name="<Name of project>.activity.Comments"
android:configChanges="orientation|keyboardHidden"
android:label="Comments"
android:screenOrientation="portrait"
android:theme="@style/AppTheme.NoActionBar"
android:windowSoftInputMode="stateHidden|adjustResize" />
Comments.xml:
<RelativeLayout
android:id="@+id/send_message"
android:layout_width="match_parent"
android:layout_height="90dp"
android:layout_margin="4dp"
android:layout_alignParentBottom="true">
<EditText
android:fontFamily="sans-serif"
android:id="@+id/write_comment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="12dp"
android:gravity="left"
android:textSize="16sp"
android:textColor="@color/black"
android:cursorVisible="false"
android:textColorHint="@color/material_color_grey_300"
android:hint="@string/commentBack"
android:background="@drawable/edittext_bg"
android:inputType="textMultiLine"
android:isScrollContainer="true"
android:maxLength="200"
android:scrollHorizontally="false" />
<Button
android:fontFamily="sans-serif-medium"
android:id="@+id/send_comment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"
android:textColor="@color/colorPrimary"
android:layout_marginTop="8dp"
android:text="@string/send"
android:background="@null"
android:layout_below="@id/write_comment"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:textAllCaps="false" />
</RelativeLayout>
我试图添加android:isScrollContainer =“true”,认为它会为EditText创建一个滚动容器,这样它有助于扩展布局,但似乎没有用.任何帮助,将不胜感激.谢谢!
编辑:根据以下答案添加整个布局:

编辑:根据Jaydroider的要求,我附上了一张照片来显示我的问题.如果我可以制作GIF或其他东西,如果我在EditText字段中添加更多文本,发送按钮将在键盘下消失,除非我从EditText中删除文本,否则无法推送发送:
编辑:我还展示了当我点击EditText时如何滚动到ListView的底部,如果这有帮助的话.
public void setupComment(final EditText comment) {
//Once we send the post, we want to scroll to bottom of listview
comment.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
if (event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
comment.setImeOptions(EditorInfo.IME_ACTION_DONE);
resetKeyboardSettings();
}
return false;
}
});
//Hide the cursor until view is clicked on
View.OnTouchListener onTouchListener = new View.OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
System.out.println("Touched");
if (v.getId() == comment.getId()) {
comment.setCursorVisible(true);
}
commentsView.postDelayed(new Runnable() {
@Override
public void run() {
commentsView.smoothScrollToPosition(commentsView.getAdapter().getCount());
}
}, 750);
return false;
}
};
comment.setOnTouchListener(onTouchListener);
}
解决方法:
我试过你的布局一切都很完美,不是问题.
But you need to make changes to your manifest where you declared your activity
using more properties toandroid:configChanges
.Do this inside your
android manifest.xml
file.
<activity
android:name="<Name of project>.activity.Comments"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="Comments"
android:screenOrientation="portrait"
android:theme="@style/AppTheme.NoActionBar"
android:windowSoftInputMode="stateHidden|adjustResize"/>
这是我使用的XML.

我已经测试了上面的变化,它只是工作正常,你可以在下面看到.
希望这能帮助您解决问题.
