我的应用程序中有两个EditTexts
并排。
这是他们使用1行输入
的样子目前,当我在一个EditText
中输入多行输入时会增长,但另一行保持相同的高度 - 如此处所示
我希望EditTexts
的高度匹配。当一个人成长时,另一个人的身高就会达到 - 就像这里看到的那样
不确定如何达到此效果。我不想用新行填写其他EditText
。我希望实际View
增长。
这是我目前的布局
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_marginTop="10dp"
android:weightSum="6"
android:orientation="horizontal">
<EditText
android:id="@+id/left"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:inputType="textMultiLine"
android:gravity="top|start"/>
<EditText
android:id="@+id/right"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:inputType="textMultiLine"
android:gravity="top|start"/>
</LinearLayout>

尝试在onTextChange方法中更改其他edittext的高度...示例
class SeasonsController < ApplicationController
before_action :authenticate_user!
before_action :ensure_admin_user!, except: [:show, :index]
...
private
def ensure_admin_user!
render_error unless current_user.admin?
end
def render_error
# whatever
end
end

请尝试以下方法,
<LinearLayout
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_marginTop="10dp"
android:layout_width="match_parent"
android:orientation="horizontal"
android:weightSum="2">
<LinearLayout
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_width="0dp"
android:orientation="vertical"
android:padding="5dp">
<EditText
android:gravity="top|start"
android:id="@+id/left"
android:inputType="textMultiLine"
android:layout_height="0dip"
android:layout_weight="1"
android:layout_width="match_parent" />
</LinearLayout>

我做了一些研究并遇到this回答。根据链接的答案,我创建了这个解决方案:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_marginTop="10dp"
android:orientation="horizontal"
android:weightSum="6">
<View
android:id="@+id/strut"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_centerHorizontal="true" />
<EditText
android:id="@+id/left"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignRight="@id/strut"
android:gravity="top|start"
android:layout_alignBottom="@+id/right"
android:inputType="textMultiLine" />
<EditText
android:id="@+id/right"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignLeft="@id/strut"
android:layout_alignParentRight="true"
android:gravity="top|start"
android:inputType="textMultiLine" />
</RelativeLayout>
在你的java代码中执行以下操作:
editTextLeft = (EditText) findViewById(R.id.left);
editTextRight = (EditText) findViewById(R.id.right);
editTextLeft.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean b) {
if (b) {
RelativeLayout.LayoutParams leftLayoutParams = (RelativeLayout.LayoutParams) editTextLeft.getLayoutParams();
RelativeLayout.LayoutParams rightLayoutParams = (RelativeLayout.LayoutParams) editTextRight.getLayoutParams();
leftLayoutParams.removeRule(RelativeLayout.ALIGN_BOTTOM);
rightLayoutParams.addRule(RelativeLayout.ALIGN_BOTTOM,editTextLeft.getId());
int lines = editTextRight.getLineCount() > editTextLeft.getLineCount() ? editTextRight.getLineCount() : editTextLeft.getLineCount();
editTextLeft.setMinLines(lines);
editTextRight.setMinLines(lines);
editTextLeft.setLayoutParams(leftLayoutParams);
editTextRight.setLayoutParams(rightLayoutParams);
}
}
});
editTextRight.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean b) {
if(b) {
RelativeLayout.LayoutParams leftLayoutParams = (RelativeLayout.LayoutParams) editTextLeft.getLayoutParams();
RelativeLayout.LayoutParams rightLayoutParams = (RelativeLayout.LayoutParams) editTextRight.getLayoutParams();
rightLayoutParams.removeRule(RelativeLayout.ALIGN_BOTTOM);
leftLayoutParams.addRule(RelativeLayout.ALIGN_BOTTOM, editTextRight.getId());
int lines = editTextRight.getLineCount() > editTextLeft.getLineCount() ? editTextRight.getLineCount() : editTextLeft.getLineCount();
editTextLeft.setMinLines(lines);
editTextRight.setMinLines(lines);
editTextLeft.setLayoutParams(leftLayoutParams);
editTextRight.setLayoutParams(rightLayoutParams);
}
}
});
