Android自定义弹出填写框

简单回调：

先上图： 

主activity 

复制代码代码如下:

package com.su.testcustomdialog; 
import com.su.testcustomdialog.MyDialog.Dialogcallback; 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 
public class CustomDialogActivity extends Activity { 
private TextView textView; 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 
textView = (TextView) findViewById(R.id.textView11); 
Button button = (Button) findViewById(R.id.button1); 
button.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View v) { 
MyDialog myDialog = new MyDialog(CustomDialogActivity.this); 
myDialog.setContent("哥来自Activity"); 
myDialog.setDialogCallback(dialogcallback); 
myDialog.show(); 
} 
}); 
} 
/** 
* 设置mydialog需要处理的事情 
*/ 
Dialogcallback dialogcallback = new Dialogcallback() { 
@Override 
public void dialogdo(String string) { 
textView.setText("哥來自Dialog: " + string); 
} 
}; 
} 

然后是MyDialog的核心了 

复制代码代码如下:

package com.su.testcustomdialog; 
import android.app.Dialog; 
import android.content.Context; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 
/** 
* 自定义dialog 
* @author sfshine 
* 
*/ 
public class MyDialog { 
Context context; 
Dialogcallback dialogcallback; 
Dialog dialog; 
Button sure; 
TextView textView; 
EditText editText; 
/** 
* init the dialog 
* @return 
*/ 
public MyDialog(Context con) { 
this.context = con; 
dialog = new Dialog(context, R.style.dialog); 
dialog.setContentView(R.layout.dialog); 
textView = (TextView) dialog.findViewById(R.id.textview); 
sure = (Button) dialog.findViewById(R.id.button1); 
editText = (EditText) dialog.findViewById(R.id.editText1); 
sure.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View v) { 
dialogcallback.dialogdo(editText.getText().toString()); 
dismiss(); 
} 
}); 
} 
/** 
* 设定一个interfack接口,使mydialog可以處理activity定義的事情 
* @author sfshine 
* 
*/ 
public interface Dialogcallback { 
public void dialogdo(String string); 
} 
public void setDialogCallback(Dialogcallback dialogcallback) { 
this.dialogcallback = dialogcallback; 
} 
/** 
* @category Set The Content of the TextView 
* */ 
public void setContent(String content) { 
textView.setText(content); 
} 
/** 
* Get the Text of the EditText 
* */ 
public String getText() { 
return editText.getText().toString(); 
} 
public void show() { 
dialog.show(); 
} 
public void hide() { 
dialog.hide(); 
} 
public void dismiss() { 
dialog.dismiss(); 
} 
} 

dialog的布局 

复制代码代码如下:

<?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="wrap_content" 
android:layout_margin="30.0dp" 
android:orientation="vertical" 
android:padding="10dip" > 
<!-- 这里如果使用android:layout_width="5000dip"设置一个极大的值 系统就会 --> 
<TextView 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_margin="30.0dp" 
android:gravity="center" 
android:text="自定义Dialog" 
android:textColor="#F0F" 
android:textSize="20dip" /> 
<TextView 
android:id="@+id/textview" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" /> 
<EditText 
android:id="@+id/editText1" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:ems="10" > 
</EditText> 
<Button 
android:id="@+id/button1" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_gravity="right" 
android:text="確定" /> 
</LinearLayout> 

style 的文件 

复制代码代码如下:

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
<style name="dialog" parent="@android:style/Theme.Dialog"> 
<item name="android:windowFrame">@null</item> 
<item name="android:windowIsFloating">true</item> 
<item name="android:windowIsTranslucent">false</item> 
<item name="android:windowNoTitle">true</item> 
<item name="android:background">#FFF</item> 
<item name="android:windowBackground">@android:color/transparent</item> 
<item name="android:backgroundDimEnabled">true</item> 
</style> 
</resources>
