因爲android原生的AlertDialog都一致,有時爲了和你的項目的Dialog保持一致,你最早想到的就是有沒有AlertDialog相關的style,但據個人查找,官方沒有提供明確的文檔來修改其樣式,因此咱們想到的是本身自定一個AlertDialogandroid
如圖,固然風格能夠本身修改api
所先把你想要的佈局custom_dialog_viewapp
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center" >
<!-- 頂部橢園邊緣 -->
<ImageView
android:layout_width="300dp"
android:layout_height="22dp"
android:src="@drawable/app_listbk_d" >
</ImageView>
<!-- 中間白色背景,兩個TextView,標題和內容,留一個LinearLayout,在代碼中根據調用動態加上按鈕 -->
<LinearLayout
android:layout_width="300dp"
android:layout_height="wrap_content"
android:background="@drawable/app_listbk_d"
android:orientation="vertical" >
<TextView
android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#000000"
android:textSize="35dp" />
<TextView
android:id="@+id/message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="10dp"
android:layout_marginTop="20dp"
android:textColor="#000000"
android:textSize="25dp" />
<!-- 在LinearLayout中加按鈕 -->
<LinearLayout
android:id="@+id/buttonLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:gravity="center"
android:orientation="horizontal" >
</LinearLayout>
</LinearLayout>
<!-- 底部橢園邊緣 -->
<ImageView
android:layout_width="300dp"
android:layout_height="22dp"
android:layout_marginTop="-2dp"
android:src="@drawable/app_listbk_d" >
</ImageView>
</LinearLayout>ide
而後藉助原生的AlertDialog來重寫一下這個控制來達到咱們的需求佈局
package com.example.testapi.widget;
import android.content.Context;
import android.graphics.Color;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.TextView;
import com.example.testapi.R;
public class AlertDialog {
Context context;
android.app.AlertDialog ad;
TextView titleView;
TextView messageView;
LinearLayout buttonLayout;
public AlertDialog(Context context) {
this.context = context;
ad = new android.app.AlertDialog.Builder(context).create();
ad.show();
// Replace the source alert dialog.
Window window = ad.getWindow();
window.setContentView(R.layout.custom_dialog_view);
titleView = (TextView) window.findViewById(R.id.title);
messageView = (TextView) window.findViewById(R.id.message);
buttonLayout = (LinearLayout) window.findViewById(R.id.buttonLayout);
}
public void setTitle(int resId)
{
titleView.setText(resId);
}
public void setTitle(String title) {
titleView.setText(title);
}
public void setMessage(int resId) {
messageView.setText(resId);
}
public void setMessage(String message)
{
messageView.setText(message);
}
/**
* Button style
*
* @param text
* @param listener
*/
public void setPositiveButton(String text, final View.OnClickListener listener)
{
Button button = new Button(context);
LinearLayout.LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
button.setLayoutParams(params);
button.setBackgroundResource(R.drawable.app_listbk);
button.setText(text);
button.setTextColor(Color.WHITE);
button.setTextSize(20);
button.setOnClickListener(listener);
buttonLayout.addView(button);
}
/**
* Button style
*
* @param text
* @param listener
*/
public void setNegativeButton(String text, final View.OnClickListener listener)
{
Button button = new Button(context);
LinearLayout.LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
button.setLayoutParams(params);
button.setBackgroundResource(R.drawable.app_listbk);
button.setText(text);
button.setTextColor(Color.WHITE);
button.setTextSize(20);
button.setOnClickListener(listener);
if (buttonLayout.getChildCount() > 0)
{
params.setMargins(20, 0, 0, 0);
button.setLayoutParams(params);
buttonLayout.addView(button, 1);
} else {
button.setLayoutParams(params);
buttonLayout.addView(button);
}
}
/**
* dismiss dialog
*/
public void dismiss() {
ad.dismiss();
}
}
這樣咱們在本身的項目中就能夠像使用原生的AlertDialog同樣正常使用了ui
final AlertDialog ad = new AlertDialog(DialogStyleActivity.this);
ad.setTitle("標題");
ad.setMessage("dkdkkdkdk順水有晨在於 在在在在在礙御用有有有地區專業分工有地介是的和無本之木工;地有膽有關有關 " +
"耨溪水源源源碼在緊俏商品22是否 2進行大躍進要核工業部");
ad.setPositiveButton("肯定", new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ad.dismiss();
Toast.makeText(DialogStyleActivity.this, "被點到肯定", Toast.LENGTH_LONG).show();
}
});
ad.setNegativeButton("取消", new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ad.dismiss();
Toast.makeText(DialogStyleActivity.this, "被點到取消", Toast.LENGTH_LONG).show();
}
});
}
this
