该应用程序将在没有任何警告的情况下编译良好。

是否可以对SVG资产使用drawableRight等?
是的。
AppCompatTextView现在支持app:DrawableReftCompat
,app:DrawableReftCompat
,app:DrawableReftCompat
,app:DrawableReftCompat
,app:DrawableReftCompat
,app:DrawableReftCompat
,app:DrawableReftCompat
和
包括在你的分级文件中
implementation 'androidx.appcompat:appcompat:1.1.0-alpha01'
在文本视图中,可以使用
app:drawableLeftCompat
app:drawableStartCompat
如果在按钮中使用app:drawableleftcompat、app:drawablestartcompat时出现问题,则需要将库更新为
因为Google似乎不会在短期内对这个问题采取任何行动,所以我不得不为我的所有应用程序想出一个更可靠的可重用的解决方案:
>
首先在应用程序的attrs.xml文件“res/values/attrs.xml”中添加自定义TextView属性:
<resources>
<declare-styleable name="CustomTextView">
<attr name="drawableStartCompat" format="reference"/>
<attr name="drawableEndCompat" format="reference"/>
<attr name="drawableTopCompat" format="reference"/>
<attr name="drawableBottomCompat" format="reference"/>
</declare-styleable>
</resources>
然后创建自定义TextView类,如下所示:
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.drawable.Drawable;
import android.os.Build;
import android.support.v7.content.res.AppCompatResources;
import android.support.v7.widget.AppCompatTextView;
import android.util.AttributeSet;
public class CustomTextView extends AppCompatTextView {
public CustomTextView(Context context) {
super(context);
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
initAttrs(context, attrs);
}
public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initAttrs(context, attrs);
}
void initAttrs(Context context, AttributeSet attrs) {
if (attrs != null) {
TypedArray attributeArray = context.obtainStyledAttributes(
attrs,
R.styleable.CustomTextView);
Drawable drawableStart = null;
Drawable drawableEnd = null;
Drawable drawableBottom = null;
Drawable drawableTop = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
drawableStart = attributeArray.getDrawable(R.styleable.CustomTextView_drawableStartCompat);
drawableEnd = attributeArray.getDrawable(R.styleable.CustomTextView_drawableEndCompat);
drawableBottom = attributeArray.getDrawable(R.styleable.CustomTextView_drawableBottomCompat);
drawableTop = attributeArray.getDrawable(R.styleable.CustomTextView_drawableTopCompat);
} else {
final int drawableStartId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableStartCompat, -1);
final int drawableEndId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableEndCompat, -1);
final int drawableBottomId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableBottomCompat, -1);
final int drawableTopId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableTopCompat, -1);
if (drawableStartId != -1)
drawableStart = AppCompatResources.getDrawable(context, drawableStartId);
if (drawableEndId != -1)
drawableEnd = AppCompatResources.getDrawable(context, drawableEndId);
if (drawableBottomId != -1)
drawableBottom = AppCompatResources.getDrawable(context, drawableBottomId);
if (drawableTopId != -1)
drawableTop = AppCompatResources.getDrawable(context, drawableTopId);
}
// to support rtl
setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, drawableTop, drawableEnd, drawableBottom);
attributeArray.recycle();
}
}
}
<YOUR_VIEW_PACKAGE.CustomTextView
android:id="@+id/edt_my_edit_text"

有没有可能用硒点击具有相同文本的乘法按钮?
我正在使用viewpager在片段之间滑动,并希望“后退”按钮导航到之前查看的片段,而不是结束活动。对不起,如果这是一个重复的问题,但我没有发现答案很有帮助。显然,onBackPressed需要重写,但我不知道如何获取和显示正确的片段。我假设我应该使用fragmentmanager的backbackback,但是使用getSupportFragmentManager()。getBackStackE
这不是一个浏览器。 我打算为我的机器人做一个“黑名单”数组,这将阻止用户运行命令。然而,我似乎只能在实际的bot文件上这样做,因为我还没有找到一种方法来做一个外部方法。 这就是我正在使用的:

问题内容: 是否可以用简单的CSS样式的按钮替换Uploadify按钮(包含向上/向上/向下状态的图形)? 问题答案: 我已经能够提出一个可行的解决方案。基本概要如下: 禁用Uploadify按钮图像 使Flash对象透明 使用CSS将伪造的样式或标签放置在Flash对象后面 初始化Uploadify后,设置对象的宽度和高度以匹配其后面的按钮 Flash对象将屏蔽其下方的按钮,使其免受鼠标悬停等事
