Android 自定义Dialog 实现类似ios7 UIAlertView

效果图

实现步骤

1.AlertDialog.java

/** *  * @author zhangwen 2014-12-22 * 只带有一个确认按钮的dialog * */public class AlertDialog extends Dialog implements OnClickListener{private TextView mTitleTv;private Button mOkBtn;private TextView mMsgTv;private OnOkClickListener mOnOkClickListener;//确定按钮监听public interface OnOkClickListener{void onOkClick();}public AlertDialog(Context context, OnOkClickListener onOkClickListener,String title,String btnText){this(context,onOkClickListener,title,null,btnText);}public AlertDialog(Context context, OnOkClickListener onOkClickListener,String title,String msg,String btnText){super(context, R.style.dialog);this.mOnOkClickListener = onOkClickListener;setContentView(R.layout.dialog_alert);mTitleTv = (TextView) findViewById(R.id.alert_title);mTitleTv.setText(title);if(msg!=null){mMsgTv = (TextView) findViewById(R.id.alert_msg_tv);mMsgTv.setText(msg);mMsgTv.setVisibility(View.VISIBLE);}mOkBtn = (Button) findViewById(R.id.alert_btn);mOkBtn.setText(btnText);mOkBtn.setOnClickListener(this);}@Overridepublic void onClick(View v) {if(mOnOkClickListener!=null){mOnOkClickListener.onOkClick();}this.dismiss();}}

2.styles.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">    <style name="dialog" parent="@android:style/Theme.Dialog">        <item name="android:windowBackground">@drawable/dialog_bg</item>        <!-- 设置自定义布局的背景透明 -->        <item name="android:windowNoTitle">true</item>    </style></resources>

3.colors.xml

<resources>    <color name="dialog_bg">#D0FFFFFF</color>    <color name="dialog_btn_h">#89b7db</color></resources>

4.dimens.xml

<resources>    <dimen name="dialog_width">260dp</dimen></resources>

5.dialog_alert.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="@dimen/dialog_width"    android:layout_height="match_parent"    android:background="@drawable/dialog_bg"    android:orientation="vertical"    android:padding="0dp" >    <TextView        android:id="@+id/alert_title"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:paddingTop="16dip"        android:paddingLeft="10dp"        android:paddingRight="10dp"        android:paddingBottom="12dp"        android:textStyle="bold"        android:textColor="#000"        android:textSize="16sp" /><TextView    android:id="@+id/alert_msg_tv"     android:layout_width="match_parent"    android:layout_height="wrap_content"    android:gravity="center"    android:textSize="13sp"    android:paddingTop="0dp"    android:paddingLeft="10dp"    android:paddingRight="10dp"    android:paddingBottom="10dp"     android:textColor="#000"     android:visibility="gone"    />    <View        android:layout_width="match_parent"        android:layout_height="1px"        android:background="#c0c0c0" />    <Button        android:id="@+id/alert_btn"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/sel_dia_btn_b"        android:gravity="center"        android:padding="12dp"        android:text="Ok"        android:textColor="#304FFE"        android:textSize="16dp" /></LinearLayout>

6 drawable dialog_bg.xml

<?xml version="1.0" encoding="UTF-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" >    <solid android:color="@color/dialog_bg" />    <corners android:radius="8dip" /></shape>

7. drawable sel_dia_btn_b.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_pressed="true">        <shape  android:shape="rectangle">            <!-- 填充的颜色 -->            <solid android:color="@color/dialog_btn_h" />            <!-- 设置按钮的四个角为弧形 -->            <!-- android:radius 弧形的半径 -->            <corners android:bottomLeftRadius="5dp" android:bottomRightRadius="5dp" />            <!-- padding：Button里面的文字与Button边界的间隔 -->            <padding android:bottom="10dp" android:left="10dp" android:right="10dp" android:top="10dp" />        </shape>    </item>    <item>        <shape android:shape="rectangle">            <!-- 填充的颜色 -->            <solid android:color="@android:color/transparent" />            <!-- 设置按钮的四个角为弧形 -->            <!-- android:radius 弧形的半径 -->            <corners android:bottomLeftRadius="5dp" android:bottomRightRadius="5dp" />            <!-- padding：Button里面的文字与Button边界的间隔 -->            <padding android:bottom="10dp" android:left="10dp" android:right="10dp" android:top="10dp" />        </shape>    </item></selector>

8.使用 MainActivity.java

//只有标题的dialognew AlertDialog(this, new OnOkClickListener() {@Overridepublic void onOkClick() {//确定按钮点击}}, "登陆失败", "确定").show();

//有描述的dialognew AlertDialog(this, new OnOkClickListener() {@Overridepublic void onOkClick() {//确定按钮点击}}, "登陆失败","此用户不存在！请检查后重新登陆", "确定").show();
