android 自定义弹出框Dialog
第一步：布局文件dialog_normal_layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:orientation="vertical"
android:padding="20dip" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/dialog_bg"
android:orientation="vertical" >
<TextView
android:id="@+id/title"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#FFFFFF"
android:gravity="center"
android:text="@string/title_alert"
android:textColor="#000000"
android:textSize="20sp"
android:visibility="visible" />
<View
android:layout_width="fill_parent"
android:layout_height="1.0px"
android:background="#ffd0d0d0" />
<Button
android:id="@+id/positiveButton"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#FFFFFF"
android:gravity="center"
android:text="@string/ok"
android:textColor="#323232"
android:textSize="18sp" />
<View
android:layout_width="fill_parent"
android:layout_height="1.0px"
android:background="#ffd0d0d0" />
<Button
android:id="@+id/neutralButton"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#FFFFFF"
android:gravity="center"
android:text="@string/yes"
android:textColor="#323232"
android:textSize="18sp" />
<View
android:layout_width="fill_parent"
android:layout_height="1.0px"
android:background="#ffd0d0d0" />
<Button
android:id="@+id/negativeButton"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#FFFFFF"
android:gravity="center"
android:text="@string/cancel"
android:textColor="#323232"
android:textSize="15sp" />
</LinearLayout>
</FrameLayout>第二步：继承Dialog
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup.LayoutParams;

public class CustomDialog extends Dialog {

this.title = title;
return this;
}
/**
* Set the positive button resource and it's listener
*
* @param positiveButtonText
* @return
*/
public Builder setPositiveButton(int positiveButtonText,
DialogInterface.OnClickListener listener) {
this.positiveButtonText = (String) context
.getText(positiveButtonText);

return this;
}
public CustomDialog create() {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// instantiate the dialog with the custom Theme
final CustomDialog dialog = new CustomDialog(context,

View layout = inflater.inflate(R.layout.dialog_normal_layout, null);

}
} else {

return dialog;

}第三步：调用弹出框
/**

* @param title 选择图片
* @param posStr 相机
* @param neuStr 相册
*/
public void showAlertDialog(Context context,String title,String posStr,String neuStr) {
CustomDialog.Builder builder = new CustomDialog.Builder(context);
builder.setTitle( title );
builder.setPositiveButton( posStr , new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
// do something about positive
}
});
builder.setNeutralButton( neuStr , new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
// do something about neutral
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create().show();
}
