Question

我有一个调用此函数的按钮，可以将View添加到我的主布局中：

private void createWrkHist() {
    View addBtn = findViewById(R.id.addWrkHist);
    RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) addBtn.getLayoutParams();
    int aboveID = params.getRule(BELOW);

    LayoutInflater inflator = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflator.inflate(R.layout.work_history_table, null);
    ViewGroup mainView = (ViewGroup) findViewById(R.id.mainForm);
    RelativeLayout.LayoutParams insertParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    insertParams.addRule(BELOW, aboveID);
    v.setLayoutParams(insertParams);
    mainView.addView(v);
    params.addRule(BELOW, R.id.wrkHist);
    addBtn.setLayoutParams(params);
}

正在添加布局，因为我使用了一些代码来尝试并专注于添加的视图上的EditText并且它有效。但是，添加的视图中的所有TextViews都是完全白色的。如何设置我添加到默认视图的样式/主题？这是我添加的布局的XML：

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/wrkHist"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <TableRow>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight=".5"
            android:text="Position:"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Small" />

        <EditText
            android:id="@+id/wrkPosition"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="5dp"
            android:layout_weight="15" />
    </TableRow>

    <TableRow>

        <TextView

            android:layout_marginStart="5dp"
            android:layout_weight="15" />

不要使用Application的上下文来创建inflater，因为它会尝试使用应用程序的主题。

使用Activity的上下文，或者使用容器的上下文，它也会为你提供Activity的上下文。

private void createWrkHist() {
    View addBtn = findViewById(R.id.addWrkHist);
    RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) addBtn.getLayoutParams();
    int aboveID = params.getRule(BELOW);

    ViewGroup mainView = (ViewGroup) findViewById(R.id.mainForm);

    LayoutInflater inflator = LayoutInflater.from(mainView.getContext());
    View v = inflator.inflate(R.layout.work_history_table, mainView, true);

    RelativeLayout.LayoutParams insertParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    insertParams.addRule(BELOW, aboveID);
    v.setLayoutParams(insertParams);
    mainView.addView(v);
    params.addRule(BELOW, R.id.wrkHist);
    addBtn.setLayoutParams(params);
}

Android addView设置TextView textColor为白色？
