Android關(guān)于自定義的dialog

首先在布局中寫出你自己想要的dialog的樣式
由于我的圖片需要平鋪 android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/note_top"
android:orientation="horizontal" >
，自己寫了一個平鋪的方法。所以在布局中看到的樣子反而不正常。在手機(jī)上能正常顯示。
實現(xiàn)平鋪的方法很簡單
public static void fixBackgroundRepeatY(View view) {
Drawable bg = view.getBackground();
if (bg != null) {
if (bg instanceof BitmapDrawable) {
BitmapDrawable bmp = (BitmapDrawable) bg;
bmp.mutate(); // make sure that we aren't sharing state anymore
bmp.setTileModeXY(null,TileMode.REPEAT);
}
}
}
接下來就開始寫java代碼了，第一步肯定是extends Dialog
直接貼代碼
public class HPDialog extends Dialog {
// 先調(diào)用構(gòu)造方法在調(diào)用oncreate方法
private static boolean isShow = true;
private Context context;
private String mYtitle;
private String mYmsg;
// private MyDialog myDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
public HPDialog() {
super(ClientEngine.getInstance().getBaseActivity());
this.context = ClientEngine.getInstance().getBaseActivity();
}
public HPDialog(Context context, int theme) {
super(context, theme);
this.context = context;
}
public void setTitle(String title) {
this.mYtitle = title;
}
public void setMsg(String msg) {
this.mYmsg = msg;
}
@Override
public void show() {
super.show();
}
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,
negativeButtonClickListener;
// private TextView msg=(TextView)findViewById(R.id.message);
public Builder(Context context) {
this.context = context;
}
public Builder setMessage(String message) {
this.message = message;
return this;
}
public Builder setMessage(int message) {
this.message = (String) context.getText(message);
return this;
}
public Builder setTitle(int title) {
this.title = (String) context.getText(title);
return this;
}
public Builder setTitle(String title) {
this.title = title;
return this;
}
public Builder setContentView(View v) {
this.contentView = v;
return this;
}
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 boolean setCancelable(boolean cancelable){
isShow = cancelable;
return isShow;
}
public Builder setNegativeButton(int negativeButtonText,
DialogInterface.OnClickListener listener) {
this.negativeButtonText = (String) context
.getText(negativeButtonText);
this.negativeButtonClickListener = listener;
return this;
}
public Builder setClickFunction(final Command[] commands) {
if(commands != null)
{
if(commands[0]==null){
this.setPositiveButton("知道了", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
}
});
}else{
this.setPositiveButton(commands[0].getLabel(), new OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
commands[0].onClick();
}
});
}
if(commands[1]!=null){
this.setNegativeButton(commands[1].getLabel(), new OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
commands[1].onClick();
}
});
}
}
return this;
}
public Builder setNegativeButton(String negativeButtonText,
DialogInterface.OnClickListener listener) {
this.negativeButtonText = negativeButtonText;
this.negativeButtonClickListener = listener;
return this;
}
public HPDialog show() {
HPDialog dialog = create();
dialog.show();
return dialog;
}
public HPDialog create() {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// instantiate the dialog with the custom Theme
final HPDialog dialog = new HPDialog(context, R.style.HPDialog);
dialog.setCanceledOnTouchOutside(false);//android 4.0以上dialog點擊其他地方也會消失false以后就只能點擊按鈕消失
View layout = inflater.inflate(R.layout.dialog, null);
ScrollView sv = (ScrollView) layout.findViewById(R.id.HpDialogScrollView);
int width = context.getResources().getDrawable(R.drawable.note_top).getIntrinsicWidth();
sv.getLayoutParams().width=width-30;
if(message!=null && message.length()>160){
sv.getLayoutParams().height=MainMenu.screenHeight*2/5;
}
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.dialog_button_ok)).setText(positiveButtonText);
if (positiveButtonClickListener != null) {
((Button) layout.findViewById(R.id.dialog_button_ok)).setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
positiveButtonClickListener.onClick(dialog,DialogInterface.BUTTON_POSITIVE);
dialog.dismiss();
}
});
}
} else {
// if no confirm button just set the visibility to GONE
layout.findViewById(R.id.dialog_button_ok).setVisibility(View.GONE);
}
if (negativeButtonText != null) {
((Button) layout.findViewById(R.id.dialog_button_cancel)).setText(negativeButtonText);
if (negativeButtonClickListener != null) {
// ((Button) layout.findViewById(R.id.dialog_button_ok)).
((Button) layout.findViewById(R.id.dialog_button_cancel)).setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
negativeButtonClickListener.onClick(dialog, DialogInterface.BUTTON_NEGATIVE);
dialog.dismiss();
}
});
}
} else {
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) ((Button) layout.findViewById(R.id.dialog_button_ok)).getLayoutParams();
params.setMargins(30, 0, 30, 0);//這個只是根據(jù)我自己的需要調(diào)節(jié)按鈕的位置。大家可以根據(jù)自己的需要來調(diào)節(jié)
params.width = width-60;
((Button) layout.findViewById(R.id.dialog_button_ok)).setLayoutParams(params);
// if no confirm button just set the visibility to GONE
layout.findViewById(R.id.dialog_button_cancel).setVisibility(View.GONE);
}
// set the cancel button
// set the content message
if (message != null) {
((TextView) layout.findViewById(R.id.msg)).setText(message);
} else if (contentView != null) {
// if no message set
// add the contentView to the dialog body
((LinearLayout) layout.findViewById(R.id.body)).removeAllViews();
((LinearLayout) layout.findViewById(R.id.body)).addView(
contentView, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
dialog.setContentView(layout);
return dialog;
}
}
}
這樣一個自定義的dialog就搞定了。用法和系統(tǒng)的一樣。只是換了個顯示樣式
