android - Android :: 从可绘制资源设置背景失败

Question

问题

我使用下面的代码膨胀了一些布局以添加到现有布局中。

API = 19 中似乎一切正常但是，低于 19 则不行。

我不知道这里发生了什么请帮我找出问题thx。

示例图片

添加任何视图之前的默认视图

示例代码

    LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflater.inflate(R.layout.temp_added_layout, null, false);

    LinearLayout llFirstDevice = (LinearLayout) findViewById(R.id.llFirstDevice);
    if (android.os.Build.VERSION.SDK_INT < 16) {
        llFirstDevice.setBackgroundResource(R.drawable.temp_top_added);
    } else {
        llFirstDevice.setBackground(getResources().getDrawable(R.drawable.temp_top_added));
    }
    llFirstDevice.addView(v, 0);

Answer 1

只需将您的形状编辑为：

<shape >
    <stroke
        android:dashGap="10dp"
        android:dashWidth="10dp"
        android:width="2dp"
        android:color="#99333333" />
    <padding
        android:bottom="@dimen/temp_added_padding_B"
        android:left="30dp"
        android:right="30dp"
        android:top="@dimen/temp_added_padding_T" />
    <solid android:color="@android:color/transparent"/> <!-- ADD THIS LINE -->
</shape>
