使用Android中的选择器项和形状来选择按钮

Question

我使用选择器和形状定义了按钮样式，并将其保存在drawable文件夹中。然后将其与布局文件中的按钮相关联。

当按下一个按钮时，按钮背景颜色已更改，但松开按钮后仍显示默认颜色。我希望选定的颜色在按钮单击后仍然保持不变。我需要帮助。提前感谢。

在drawable / highscore_button_style.xml中的按钮样式

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" >
        <shape android:shape="rectangle" >
            <solid android:color="@color/high_score_btn_bg_selected" />
            <corners android:radius="5dp" />
            <stroke android:color="@color/high_score_btn_bg_selected" android:width="1dp" />
        </shape>
    </item>
    <item android:state_pressed="true" >
        <shape android:shape="rectangle" >
            <solid android:color="@color/high_score_btn_bg_selected" />
            <corners android:radius="5dp" />
            <stroke android:color="@color/high_score_btn_bg_selected" android:width="1dp" />
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle" >
            <solid android:color="@color/high_score_btn_bg" />
            <corners android:radius="5dp" />
            <stroke android:color="@color/high_score_btn_bg" android:width="1dp" />
        </shape>
    </item>
</selector>

在布局文件中添加按钮：

<Button
    android:id="@+id/btnLevel1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/highscore_button_style"
    android:layout_marginRight="1dp"
    android:paddingTop="5dp"
    android:paddingBottom="5dp"
    android:layout_weight="1"
    android:text="1"
    android:textColor="@color/high_score_btn_text" />
<Button
    android:id="@+id/btnLevel2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/highscore_button_style"
    android:layout_marginRight="1dp"
    android:paddingTop="5dp"
    android:paddingBottom="5dp"
    android:layout_weight="1"
    android:text="2"
    android:textColor="@color/high_score_btn_text" />
<Button
    android:id="@+id/btnLevel3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/highscore_button_style"
    android:layout_marginRight="1dp"
    android:paddingTop="5dp"
    android:paddingBottom="5dp"
    android:layout_weight="1"
    android:text="3"
    android:textColor="@color/high_score_btn_text" />

在 .java 文件中添加以下代码

Button btn =(Button) findViewById(R.id.btnLevel1);
btn.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
    v.setSelected(true);
    // code here 
  }
});
