Android 5.0 のアプリでスイッチをクリックすると、以下に示す logcat でアプリがクラッシュします。logcat は私のコードをどこにも参照しておらず、このスイッチは以前のすべてのバージョンで正常に機能しました。スイッチは背景色以外は見えず、クリックするとクラッシュします。

テスト後、setOnCheckedChangeListener 関数を定義するかどうかにかかわらず、同じことが起こります。スイッチがレイアウトにあっても、コードにない場合でも、クリックするとクラッシュします。

問題のスイッチの 1 つ:

<Switch
    android:layout_width="90dp"
    android:layout_height="wrap_content"
    android:textOff="Airborn"
    android:textOn="Direct Contact"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:id="@+id/switchWind"/>

で、参考にしたのがこちら。

// Doesn't actually matter since same thing happens without this
Switch sWind = (Switch) findViewById(R.id.switchWind);
sWind.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton v, boolean isChecked) {
        // Won't reach here
    }
});

マニフェスト ファイルのテーマを変更するとうまくいきました。私は android:theme="@android:style/Theme.NoTitleBar" を持っていました

それを
android:theme="@android:style/Theme.DeviceDefault"に変更しました

Android 5.0.2 を搭載した Sony タブレットで同じ問題に直面しました - アクティビティ スタイルが NoTitleBar / FullScreen の場合、スイッチがアプリをクラッシュさせます。

私にとってうまくいったのは、フルスクリーンモードをマニフェスト内ではなくコードで設定することです。

View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

何かを台無しにしなければ、結果は通常と同じですが、クラッシュはありません。
