我正在尝试使用带有EditText的android.support.design.widget.TextInputLayout进行密码输入.一旦密码输入出现问题,TextInputLayout应显示错误消息.

当我使用EditText时,setError(字符串)出现崩溃.

在我的应用程序中,我有一个链接.点击链接后,我想将用户发送到Google Play并自动更新应用.

我试过这个:

// package name from menifest: com.infibond.infi
public void installInfiApplication(View view){
    final String apkurl = "market://details?id=" + "com.infibond.infi";
    final Uri marketUri = Uri.parse(apkurl);

    Intent promptInstall = new Intent(Intent.ACTION_VIEW).setData(marketUri);
    startActivity(promptInstall);
}

但这会将用户发送到商店而不更新应用程序.

有办法吗？如果是,那么它是什么？

我正在尝试用wave动画创建一个按钮。我不想更改图像的大小，而是要从图片和外部进行波浪效果。

我尝试了这个：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<objectAnimator
    android:propertyName="scaleX"
    android:duration="2000"
    android:valueFrom="1.0"
    android:valueTo="1.3"
    android:repeatMode="reverse"
    android:repeatCount="infinite"
    android:valueType="floatType" />

<objectAnimator
    android:propertyName="scaleY"
    android:duration="2000"
    android:valueFrom="1.0"
    android:valueTo="1.3"
    android:repeatMode="reverse"
    android:repeatCount="infinite"
    android:valueType="floatType" />

但这会更改图像的大小，而不是发送图像。

我想要这样的东西：
