Question

今天，我正在使用最新的Android 7.1功能应用程序快捷方式制作应用程序。起初，它在Android 7.1.1上运行良好。但是，当我在Android M上的MIUI 8上运行时，不幸的是它崩溃了。我写了一些东西让它在M或更低版本上运行，但它再次破裂。我很困惑。我希望有人可以帮我解决这个问题。如果有人可以帮助我，我将不胜感激。不管怎么说，还是要谢谢你！

这是我的代码。

findViewById(R.id.textView5).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            addshortcut();
        }
    });
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        shortcutManager = getSystemService(ShortcutManager.class);
    }


public void addshortcut(){
    TextView textView = (TextView)findViewById(R.id.textView5);
    String name = textView.getText().toString();
    ShortcutInfo dynamicShortcut = null;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N_MR1) {
        dynamicShortcut = new ShortcutInfo.Builder(this, "shortcut_dynamic-zty")
                .setShortLabel(name)
                .setLongLabel(name)
                .setIcon(Icon.createWithResource(this,R.drawable.ic_account_circle))
                .setIntents(
                        new Intent[]{
                                new Intent(Intent.ACTION_VIEW, Uri.EMPTY,com.zengtianyu.gallery1.DetailZTY.this, DetailZTY.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK),
                        })
                .build();
    }
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N_MR1) {
        shortcutManager.setDynamicShortcuts(Arrays.asList(dynamicShortcut));
    }
    Toast.makeText(this,"添加成功",Toast.LENGTH_SHORT).show();
}

这是日志。

Answer 1

您正在传递ShortcutManager.class而不是字符串常量SHORTCUT_SERVICE 将第8行更改为以下内容：

shortcutManager = (ShortcutManager)getSystemService(SHORTCUT_SERVICE);

如果您希望支持较旧的Android版本，请不要将shortcutManager设为全局变量，而是在addShortcut（）函数中创建它，并将该函数的用法包含在第7行的sdk版本检查中
所以你最终应该：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    addShortcut();
}
...
public void addShortcut(){
    ShortcutManager shortcutManager = (ShortcutManager)getSystemService(SHORTCUT_SERVICE);
    ...
}
