魅族设备 TextInputLayout 崩溃 #11
Comments

同样遇到这个问题。 Context
这个事情最终确定为：只要使用 TextInputLayout 包裹 TextInputEditText (谷歌推荐的组合，能够更好地适配 extra UI)，在魅族部分系统上就会闪退。据说 TextInputLayout + AppCompatEditText。 我这边遇到更多魅族设备存在这个问题，包括 M5s。 魅族员工答复大意就是说，魅族已经修复这个问题了，但由于固件下沉很慢，实际上效果很不尽人意。
按照现在的状况，大概率最终 28.0.0 正式版也会有这个问题，因为这事根本没法和谷歌反馈，总不能说：你们去买台魅族旧设备来试试，它们不兼容你们最新的 support 库 😥。 如果魅族的开发同学能够一起来写一个 workaround 提交给谷歌 support library，或许可以避免这个问题之后更大范围的影响。因为大家都是升级后遇到线上崩溃才后知后觉，而且还要探究折腾一番才知道是源于魅族系统的修改所致。 |

我这里有一个（可能的）解决方案，同时不会有log警告和功能不全： package android.support.design.widget
import android.content.Context
import android.os.Build
import android.util.AttributeSet
import android.widget.TextView
class FixedTextInputEditText(context: Context, attrs: AttributeSet?) : TextInputEditText(context, attrs) {
override fun getHint(): CharSequence? {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
return super.getHint()
}
return try {
getSuperHintHack()
} catch (e: Exception) {
super.getHint()
}
}
private fun getSuperHintHack(): CharSequence? {
val f = TextView::class.java.getDeclaredField("mHint")
f.isAccessible = true
return f.get(this) as? CharSequence
}

Greetings from Russian developers =) Thank you for this solution, it really works. I`am using MX6 as my main device and found that issue while testing new project. Only your type of workaround helped me. |
And another thanks from Ukrainian developers :) |
Java version of the code from @mariotaku , code specific for Meizu devices only, I think it's safer this way, for the problems the java reflection can bring. Good job @mariotaku |

Thanks for the explanations and workarounds! In my own project, I've tried out a different workaround, which doesn't use reflection. It's still a bit hacky though 😄
private void hackFixHintsForMeizu(TextInputEditText... editTexts) {
String manufacturer = Build.MANUFACTURER.toUpperCase(Locale.US);
if (manufacturer.contains("MEIZU")) {
for (TextInputEditText editText : editTexts) {
editText.setHintTextColor(Color.TRANSPARENT);
editText.setHint(editText.getHint());
}
}
} |

把 <android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="...">
<android.support.v7.widget.AppCompatEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.design.widget.TextInputLayout> |

This was just fixed in the material components for Android lib, see: material-components/material-components-android#358 |
|
这个issue是不是已经被修复了？我在mx6上重现不出来 |
TextInputLayout 内嵌 TextInputEditText 例如:
正常展示页面
应用崩溃
MEIZU E3 7.1.1
MX6 6.0
将
android.support.design.widget.TextInputEditText更换为android.support.v7.widget.AppCompatEditText不再闪退相关 so 链接: https://stackoverflow.com/questions/51891415/nullpointerexception-on-meizu-devices-in-editor-updatecursorpositionmz/52001305
