51工具盒子1.实现效果 {#1.%E5%AE%9E%E7%8E%B0%E6%95%88%E6%9E%9C}
2.定义 dialog.xml (res/layout/dialog.xml) {#2.%E5%AE%9A%E4%B9%89dialog.xml-(res%2Flayout%2Fdialog.xml)}
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >&lt;RelativeLayout android:layout_width="250sp" android:layout_height="270sp" android:layout_centerInParent="true"&gt; &lt;TextView android:id="@+id/dialog_title" android:layout_width="wrap_content" android:layout_height="35sp" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="15sp" android:textColor="#333333" android:textSize="17sp" /&gt; &lt;TextView android:id="@+id/dialog_message" android:layout_width="wrap_content" android:layout_height="160sp" android:layout_centerInParent="true" android:layout_marginTop="65sp" android:textColor="#333333" android:textSize="17sp" /&gt; &lt;LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:layout_marginTop="30sp" android:layout_marginBottom="20sp" android:orientation="horizontal"&gt; &lt;LinearLayout android:id="@+id/dialog_confirm" android:layout_width="wrap_content" android:layout_height="wrap_content"&gt; &lt;TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/confirm_button_style" android:gravity="center" android:text="确定" android:textColor="@color/white" android:textSize="18sp" /&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/dialog_cancel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="22sp"&gt; &lt;TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/cancel_button_style" android:gravity="center" android:text="取消" android:textColor="@color/teal_200" android:textSize="18sp" /&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; &lt;/RelativeLayout&gt;
</RelativeLayout>
3. 设置确定、取消按钮的background {#3.-%E8%AE%BE%E7%BD%AE%E7%A1%AE%E5%AE%9A%E3%80%81%E5%8F%96%E6%B6%88%E6%8C%89%E9%92%AE%E7%9A%84background}
上文的dialog.xml中，确定和取消按钮都是TextView，所以需要自定义按钮的背景
confirm_button_style.xml (所有的color需要自定义)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="1000sp"/>
<solid android:color="@color/teal_200"/>
<stroke
android:width="0.5sp"
android:color="@color/colorAccent"/>
<size android:width="105sp" android:height="40sp"/>
</shape>
cancel_button_style.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="1000sp"/>
<solid android:color="@color/white"/>
<stroke
android:width="0.5sp"
android:color="@color/teal_200"/>
<size android:width="105sp" android:height="40sp"/>
</shape>
4. 自定义dialog的使用 {#4.-%E8%87%AA%E5%AE%9A%E4%B9%89dialog%E7%9A%84%E4%BD%BF%E7%94%A8}
final AlertDialog dialog = new AlertDialog.Builder(xxxClass.this).create(); dialog.setCancelable(false); //点击对话框以外的位置，不消失 dialog.show();Window window = dialog.getWindow(); window.setContentView(R.layout.dialog); //标题 TextView title = window.findViewById(R.id.dialog_title); title.setText("dialog_title");
//内容 TextView message = window.findViewById(R.id.dialog_message); message.setText("dialog_message ");
//确定按钮 LinearLayout confirm = window.findViewById(R.id.dialog_confirm); confirm.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //xxx } });
//取消按钮 LinearLayout cancel = window.findViewById(R.id.dialog_cancel); cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //xxx } });
