Java PreferenceFragment与PreferencesActivity中的工具栏重叠

我的问题是我的首选项片段与工具栏重叠。由于我没有该片段来自的布局活动，因此无法应用我在其他地方看到的解决方案。我跳过并删除了pref_header.xml，除工具栏外，其他一切都正常工作

PreferenceActivity.xml

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getFragmentManager().beginTransaction()
            .replace(android.R.id.content, new GeneralPreferenceFragment())
            .commit();

}@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public static class GeneralPreferenceFragment extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref_general);
        setHasOptionsMenu(true);

        // Bind the summaries of EditText/List/Dialog/Ringtone preferences
        // to their values. When their values change, their summaries are
        // updated to reflect the new value, per the Android Design
        // guidelines.
        bindPreferenceSummaryToValue(findPreference("bredd"));
        bindPreferenceSummaryToValue(findPreference("höjd"));
        bindPreferenceSummaryToValue(findPreference("vecka"));
        bindPreferenceSummaryToValue(findPreference("klass"));


    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == android.R.id.home) {
            startActivity(new Intent(getActivity(), PreferencesActivity.class));
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    Toolbar bar;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
        LinearLayout root = (LinearLayout) findViewById(android.R.id.list).getParent().getParent().getParent();
        bar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.settings_toolbar, root, false);
        root.addView(bar, 0); // insert at top
    } else {
        ViewGroup root = (ViewGroup) findViewById(android.R.id.content);
        ListView content = (ListView) root.getChildAt(0);

        root.removeAllViews();

        bar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.settings_toolbar, root, false);


        int height;
        TypedValue tv = new TypedValue();
        if (getTheme().resolveAttribute(R.attr.actionBarSize, tv, true)) {
            height = TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
        } else {
            height = bar.getHeight();
        }

        content.setPadding(0, height, 0, 0);

        root.addView(content);
        root.addView(bar);
    }
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

}

您必须使用setPadding将preferenceFragment/Activity的内置“列表”设置得更低

请尝试以下代码：

     //Put this line in onCreate
    getListView().setPadding(0, (int) getTypedValueInDP(50), 0, 0);

   private float getTypedValueInDP(float value) {
    return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, value, getResources().getDisplayMetrics());
}

“错误的第二个参数类型。在getTypedValueInDP上找到'float'，必需的'int'。另外，我应该用什么来代替上下文？很抱歉，我是初学者：）@MartinR.L。我刚刚编辑了我的答案。请立即尝试。如果getResources（）不起作用，请尝试getActivity（）。getResources（）；好吧，代码现在编译得很好，但遗憾的是根本没有任何实际效果：/我也尝试过类似的代码，但也没有结果。
