android自定义dialog

开发中经常会用到dialog，各种各样的，觉得还是写个通用的自定义dialog，以后直接套用，在这里贴上代码，为了方便以后查阅。

先看效果图



EditDialog.java

public class EditDialog extends Dialog {

public EditDialog(Context context) {
super(context);
}

public EditDialog(Context context, int theme) {
super(context, theme);
}

public static class Builder {
private Context context;
private String title;

public Builder setEditText(String text) {
editText = text;
return this;
}

public EditText getmEditTextView() {
return mEditTextView;
}

private EditText mEditTextView;
private String editText;
private String positiveButtonText;
private String negativeButtonText;
private View contentView;
private DialogInterface.OnClickListener positiveButtonClickListener;
private DialogInterface.OnClickListener negativeButtonClickListener;

public Builder(Context context) {
this.context = context;
}

/**
* 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 EditDialog create() {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// instantiate the dialog with the custom Theme
final EditDialog dialog = new EditDialog(context,R.style.edit_dialog);
View layout = inflater.inflate(R.layout.edit_dialog_layout, null);
dialog.addContentView(layout, new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
// set the dialog title
((TextView) layout.findViewById(R.id.title)).setText(title);
mEditTextView = (EditText) layout.findViewById(R.id.editText);
((EditText) layout.findViewById(R.id.editText)).setText(editText);
// 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 (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 ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
}
dialog.setContentView(layout);
return dialog;
}
}
}

edit_dialog_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/edit_dialog_bg"
android:orientation="vertical"
android:minWidth="300dp"
>

<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_gravity="center_horizontal"
android:text="@string/edit_guide"
android:textColor="@color/public_text_black"
android:textSize="15sp" />

<LinearLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="@dimen/dp_70"
android:layout_margin="@dimen/dp_10"
android:background="@drawable/edit_bg">

<EditText
android:id="@+id/editText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:background="@null"
android:textColor="@color/public_text_black"
android:textSize="13sp"
android:gravity="top"
android:textCursorDrawable="@null"/>
</LinearLayout>

<LinearLayout
android:layout_width="match_parent"
android:layout_height="@dimen/dp_60"
android:layout_gravity="bottom"
android:gravity="center"
android:orientation="horizontal">

<Button
android:id="@+id/negativeButton"
android:layout_width="0dp"
android:layout_height="@dimen/dp_40"
android:gravity="center"
android:layout_weight="1"
android:layout_marginLeft="@dimen/dp_10"
android:layout_marginRight="@dimen/dp_10"
android:text="@string/cancel"
android:textColor="@color/public_text_gray"
android:textSize="@dimen/size_15"
android:background="@drawable/edit_button_bg"/>

<Button
android:id="@+id/positiveButton"
android:layout_width="0dp"
android:layout_height="@dimen/dp_40"
android:layout_marginLeft="@dimen/dp_10"
android:layout_marginRight="@dimen/dp_10"
android:layout_weight="1"
android:gravity="center"
android:text="@string/ok"
android:textColor="@color/public_orange"
android:textSize="@dimen/size_15"
android:background="@drawable/edit_button_bg"/>

</LinearLayout>
</LinearLayout>

最后贴上使用这个dialog的地方

final EditDialog.Builder builder = new EditDialog.Builder(this);
builder.setTitle("编辑导语");
builder.setEditText("helloword");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
String edit = builder.getmEditTextView().getText().toString();
Log.i("shenlong","edit="+edit);
}
});

builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
});

builder.create().show();

如果自己实现出来效果不好，应该是有些东西没有设置好，这里是源码地址。
