android自定義彈出框樣式實現
阿新 • • 發佈：2018-12-23
前言：
做專案時，感覺android自帶的彈出框樣式比較醜，很多應用都是自己做的彈出框，這裡也試著自己做了一個。
廢話不說先上圖片：
實現機制
1.先自定義一個彈出框的樣式
2.自己實現CustomDialog類，繼承自Dialog，實現裡面方法，在裡面載入自定義樣式的彈出框；
3.使用時，與使用Dialog一樣
具體程式碼
dialog_normal_layout.xml樣式檔案
<?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="20.0dip" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:background="@drawable/bg_bombbox" android:orientation="vertical" > <TextView android:id="@+id/title" style="@style/text_18_ffffff" android:layout_width="fill_parent" android:layout_height="40.0dip" android:gravity="center" android:text="@string/title_alert" android:visibility="visible" /> <LinearLayout android:id="@+id/content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" > <TextView android:id="@+id/message" style="@style/text_16_666666" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="left|center" android:lineSpacingMultiplier="1.5" android:minHeight="120.0dip" android:paddingBottom="15.0dip" android:paddingLeft="20.0dip" android:paddingRight="20.0dip" android:paddingTop="15.0dip" /> </LinearLayout> <View android:layout_width="fill_parent" android:layout_height="1.0px" android:background="#ffd0d0d0" /> <LinearLayout android:layout_width="fill_parent" android:layout_height="60.0dip" android:layout_gravity="bottom" android:background="@drawable/dialog_bottom_bg" android:gravity="center" android:orientation="horizontal" > <Button android:id="@+id/positiveButton" style="@style/text_15_ffffff_sdw" android:layout_width="114.0dip" android:layout_height="40.0dip" android:background="@drawable/btn_ok_selector" android:gravity="center" android:text="@string/ok" /> <Button android:id="@+id/negativeButton" style="@style/text_15_666666_sdw" android:layout_width="114.0dip" android:layout_height="40.0dip" android:layout_marginLeft="20.0dip" android:background="@drawable/btn_cancel_selector" android:gravity="center" android:text="@string/cancel" /> </LinearLayout> </LinearLayout> </FrameLayout>
其中引用的樣式檔案styles.xml
<?xml version="1.0" encoding="utf-8"?> <resources xmlns:android="http://schemas.android.com/apk/res/android"> <style name="AppBaseTheme" parent="android:Theme.Light"></style> <style name="AppTheme" parent="AppBaseTheme"></style> <style name="text_18_ffffff"> <item name="android:textSize">18.0dip</item> <item name="android:textColor">#ffffffff</item> </style> <style name="text_16_666666"> <item name="android:textSize">16.0dip</item> <item name="android:textColor">#ff666666</item> </style> <style name="sdw_white"> <item name="android:shadowColor">#7fffffff</item> <item name="android:shadowDx">0.0</item> <item name="android:shadowDy">0.65</item> <item name="android:shadowRadius">1.0</item> </style> <style name="sdw_79351b"> <item name="android:shadowColor">#ff79351b</item> <item name="android:shadowDx">0.0</item> <item name="android:shadowDy">1.0</item> <item name="android:shadowRadius">1.0</item> </style> <style name="text_15_ffffff_sdw" parent="@style/sdw_79351b"> <item name="android:textSize">15.0dip</item> <item name="android:textColor">#ffffffff</item> </style> <style name="text_15_666666_sdw" parent="@style/sdw_white"> <item name="android:textSize">15.0dip</item> <item name="android:textColor">#ff666666</item> </style> <style name="Dialog" parent="android:style/Theme.Dialog"> <item name="android:background">#00000000</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowNoTitle">true</item> <item name="android:windowIsFloating">true</item> </style> </resources>
自定義Dialog的實現類CustomDialog
package com.dyr.custom; 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; import android.widget.Button; import android.widget.LinearLayout; import android.widget.TextView; import com.dyr.view.R; public class CustomDialog extends Dialog { public CustomDialog(Context context) { super(context); } public CustomDialog(Context context, int theme) { super(context, theme); } public static class Builder { private Context context; private String title; private String message; private String positiveButtonText; private String negativeButtonText; private View contentView; private DialogInterface.OnClickListener positiveButtonClickListener; private DialogInterface.OnClickListener negativeButtonClickListener; public Builder(Context context) { this.context = context; } public Builder setMessage(String message) { this.message = message; return this; } /** * Set the Dialog message from resource * * @param title * @return */ public Builder setMessage(int message) { this.message = (String) context.getText(message); return this; } /** * Set the Dialog title from resource * * @param title * @return */ public Builder setTitle(int title) { this.title = (String) context.getText(title); return this; } /** * Set the Dialog title from String * * @param title * @return */ public Builder setTitle(String title) { this.title = title; return this; } public Builder setContentView(View v) { this.contentView = v; 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); this.positiveButtonClickListener = listener; return this; } public Builder setPositiveButton(String positiveButtonText, DialogInterface.OnClickListener listener) { this.positiveButtonText = positiveButtonText; this.positiveButtonClickListener = listener; return this; } public Builder setNegativeButton(int negativeButtonText, DialogInterface.OnClickListener listener) { this.negativeButtonText = (String) context .getText(negativeButtonText); this.negativeButtonClickListener = listener; return this; } public Builder setNegativeButton(String negativeButtonText, DialogInterface.OnClickListener listener) { this.negativeButtonText = negativeButtonText; this.negativeButtonClickListener = listener; 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,R.style.Dialog); View layout = inflater.inflate(R.layout.dialog_normal_layout, null); dialog.addContentView(layout, new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); // set the dialog title ((TextView) layout.findViewById(R.id.title)).setText(title); // set the confirm button if (positiveButtonText != null) { ((Button) layout.findViewById(R.id.positiveButton)) .setText(positiveButtonText); if (positiveButtonClickListener != null) { ((Button) layout.findViewById(R.id.positiveButton)) .setOnClickListener(new View.OnClickListener() { public void onClick(View v) { positiveButtonClickListener.onClick(dialog, DialogInterface.BUTTON_POSITIVE); } }); } } else { // if no confirm button just set the visibility to GONE layout.findViewById(R.id.positiveButton).setVisibility( View.GONE); } // set the cancel button if (negativeButtonText != null) { ((Button) layout.findViewById(R.id.negativeButton)) .setText(negativeButtonText); if (negativeButtonClickListener != null) { ((Button) layout.findViewById(R.id.negativeButton)) .setOnClickListener(new View.OnClickListener() { public void onClick(View v) { negativeButtonClickListener.onClick(dialog, DialogInterface.BUTTON_NEGATIVE); } }); } } else { // if no confirm button just set the visibility to GONE layout.findViewById(R.id.negativeButton).setVisibility( View.GONE); } // set the content message if (message != null) { ((TextView) layout.findViewById(R.id.message)).setText(message); } else if (contentView != null) { // if no message set // add the contentView to the dialog body ((LinearLayout) layout.findViewById(R.id.content)) .removeAllViews(); ((LinearLayout) layout.findViewById(R.id.content)) .addView(contentView, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); } dialog.setContentView(layout); return dialog; } } }
使用程式碼
CustomDialog.Builder builder = new CustomDialog.Builder(this);
builder.setMessage("這個就是自定義的提示框");
builder.setTitle("提示");
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
//設定你的操作事項
}
});
builder.setNegativeButton("取消",
new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create().show();至此，自定義彈出框已經完成，是不是感覺很簡單呢。
