安卓自定义Dialog之BaseDialog
项目里用到的dialog越来越多，样式也各式各样，为了方便，所以就考虑写一个BaseDialog。
新建BaseDialog继承Dialog
public class BaseDialog extends Dialog {
public BaseDialog(Context context) {
super(context);
}
public BaseDialog(Context context, int themeResId) {
super(context, themeResId);
}
protected BaseDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
super(context, cancelable, cancelListener);
}
}我们也仿造dialog的来设计，利用Builder模式
静态成员类（嵌套类）
public static class Builder {
private Context context;
private boolean cancelable = false;
private OnCancelListener cancelListener;
private int theme = R.style.commonDialog;
private CharSequence positionText;
private CharSequence negativeText;
private OnClickListener positiveListener;
private OnClickListener negativeListener;
private View centerView;
private CharSequence title;
private LayoutParams centerLP = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
private Map viewMap;
}
public Builder(Context context) {
this.context = context;
viewMap = new HashMap();
}
public Context getContext() {
return context;
}
public Builder setCancelable(boolean cancelable) {
this.cancelable = cancelable;
return this;
}
public Builder setCancelListener(OnCancelListener cancelListener) {
this.cancelListener = cancelListener;
return this;
}
public Builder setTheme(int theme) {
this.theme = theme;
return this;
}
public Builder setTitle(CharSequence title) {
this.title = title;
return this;
}
public Builder setTitle(int textId) {
this.title = getContext().getString(textId);
return this;
}
public Builder setCenterView(View centerView) {
this.centerView = centerView;
return this;
}
public Builder setCenterView(int resId) {
this.centerView = View.inflate(getContext(), resId, null);
return this;
}
public Builder setPositiveButton(int textId, OnClickListener listener) {
this.positionText = getContext().getString(textId);
this.positiveListener = listener;
return this;
}
public Builder setPositiveButton(CharSequence text, OnClickListener listener) {
this.positionText = text;
this.positiveListener = listener;
return this;
}
public Builder setNegativeButton(int textId, OnClickListener listener) {
this.negativeText = getContext().getString(textId);
;
this.negativeListener = listener;
return this;
}
public Builder setNegativeButton(CharSequence text, OnClickListener listener) {
this.negativeText = text;
this.negativeListener = listener;
return this;
} R.layout.common_base_dialog

对外的create方法
public Dialog create() {
final Dialog dialog = new Dialog(getContext(), theme);
dialog.setCancelable(cancelable);
dialog.setOnCancelListener(cancelListener);
View view = View.inflate(getContext(), R.layout.common_base_dialog, null);
dialog.setContentView(view);
TextView tv_title = (TextView) view.findViewById(R.id.tv_title);
if (!TextUtils.isEmpty(title)) {
tv_title.setText(title);
}
ImageView iv_cancel = (ImageView) view.findViewById(R.id.iv_cancel);
if (cancelable) {
iv_cancel.setVisibility(View.VISIBLE);
iv_cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.cancel();
if (cancelListener != null) {
cancelListener.onCancel(dialog);
}
}
});
} else {
iv_cancel.setVisibility(View.GONE);
}
if (TextUtils.isEmpty(positionText) && TextUtils.isEmpty(negativeText)) {
view.findViewById(R.id.lay_bottom).setVisibility(View.GONE);
} else {
View bottomView = view.findViewById(R.id.lay_bottom);
bottomView.setVisibility(View.VISIBLE);
Button btn_positive = (Button) bottomView.findViewById(R.id.btn_positive);
Button btn_negative = (Button) bottomView.findViewById(R.id.btn_negative);
if (TextUtils.isEmpty(positionText)) {
btn_positive.setVisibility(View.GONE);
} else {
btn_positive.setVisibility(View.VISIBLE);
btn_positive.setText(positionText);
btn_positive.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
if (positiveListener != null) {
positiveListener.onClick(dialog, BUTTON_POSITIVE);
}
}
});
}
if (TextUtils.isEmpty(negativeText)) {
btn_negative.setVisibility(View.GONE);
} else {
btn_negative.setVisibility(View.VISIBLE);
btn_negative.setText(negativeText);
btn_negative.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
if (negativeListener != null) {
negativeListener.onClick(dialog, BUTTON_NEGATIVE);
}
}
});
}
if (!TextUtils.isEmpty(positionText) && !TextUtils.isEmpty(negativeText)) {
btn_negative.setBackgroundResource(R.drawable.common_selector_dialog_press_white);
btn_positive.setBackgroundResource(R.drawable.common_selector_dialog_press_blue);
}
}
ViewGroup centerLay = (ViewGroup) view.findViewById(R.id.lay_center);
centerView = getCenterView(centerView, centerLay);
if (centerView != null) {
centerView.setLayoutParams(centerLP);
centerLay.addView(centerView);
}
initDialogSize(dialog);
return dialog;
}
private void initDialogSize(Dialog dialog) {
DisplayMetrics metrics = getContext().getResources().getDisplayMetrics();
android.view.WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width = (int) (metrics.widthPixels - 10 * 2 * metrics.density);
params.height = android.view.WindowManager.LayoutParams.WRAP_CONTENT;
}
protected View getCenterView(View centerView, ViewGroup container) {
return centerView;
}好了，BaseDialog的代码就这么多
在activity使用
public class DialogActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dialog);
}
public Dialog connectDeviceWarn(final Context context, final DialogInterface.OnClickListener onClickListener) {
return normal(context, "标题", "要提示的msg", "确定按钮的text", "取消按钮的text", onClickListener);
}
public Dialog normal(final Context context, String title, String msg, String okText,
String cancelText, final DialogInterface.OnClickListener onClickListener) {
BaseDialog.Builder builder = new BaseDialog.Builder(context) {
@Override
protected View getCenterView(View centerView, ViewGroup container) {
return centerView;
}
};
View view = View.inflate(context, R.layout.common_warn_dialog, null);
((TextView) view.findViewById(R.id.dialog_hint)).setText(msg);
builder.setCenterView(view);
if (!TextUtils.isEmpty(okText)) {
builder.setPositiveButton(okText, onClickListener);
}
builder.setNegativeButton(cancelText, null);
builder.setTitle(title);
return builder.create();
}
public void baseDialog(View view){
connectDeviceWarn(DialogActivity.this, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//
}
}).show();
}
}实际使用时可以把一种dialog写成一个工具类，那就可以随便使用了，如下
public class WarnDialog {
/**
* 确认提交警告
**/
public static Dialog submitWarn(final Context context, Spanned wareDesc,
final DialogInterface.OnClickListener onClickListener) {
BaseDialog.Builder builder = new BaseDialog.Builder(context) {
@Override
protected View getCenterView(View centerView, ViewGroup container) {
return centerView;
}
};
View view = View.inflate(context, R.layout.common_warn_dialog, null);
((TextView) view.findViewById(R.id.dialog_hint)).setText(wareDesc);
builder.setCenterView(view)
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
onClickListener.onClick(dialog, which);
}
})
.setNegativeButton("取消", null);
builder.setTitle("提示");
return builder.create();
}
public static Dialog submitWarn(final Context context, String wareDesc,
final DialogInterface.OnClickListener onClickListener) {
return normal(context, "提示", wareDesc, "确定", "取消", onClickListener);
}
/**
* 确认退出登录警告
**/
public static Dialog logout(final Activity context, final DialogInterface.OnClickListener onClickListener) {
return normal(context, "提示", "确认退出登录？", "确定", "取消", onClickListener);
}
/**
* 未连接设备警告对话框
**/
public static Dialog connectDeviceWarn(final Context context, final DialogInterface.OnClickListener onClickListener) {
return normal(context, "提示", "当前未连接到设备，是否设置连接设备？", "去连接", "取消", onClickListener);
}
/**
* 确认通用警告
**/
public static Dialog normal(final Context context, String title, String msg, String okText,
String cancelText, final DialogInterface.OnClickListener onClickListener) {
BaseDialog.Builder builder = new BaseDialog.Builder(context) {
@Override
protected View getCenterView(View centerView, ViewGroup container) {
return centerView;
}
};
View view = View.inflate(context, R.layout.common_warn_dialog, null);
((TextView) view.findViewById(R.id.dialog_hint)).setText(msg);
builder.setCenterView(view);
if (!TextUtils.isEmpty(okText)) {
builder.setPositiveButton(okText, onClickListener);
}
builder.setNegativeButton(cancelText, null);
builder.setTitle(title);
return builder.create();
}
/**
* 退出编辑警告
**/
public static Dialog exitEdit(final Activity context) {
return normal(context, "提示", "确认退出编辑？", "确定", "取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
context.finish();
}
});
}
}上面activity的代码就可以改为：
public class DialogActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dialog);
}
public void baseDialog(View view){
WarnDialog.connectDeviceWarn(DialogActivity.this, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showWarnDialog("确认退出？");
}
}).show();
}
private void showWarnDialog(String warnDesc) {
WarnDialog.submitWarn(context, warnDesc, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//做处理
}
}).show();
}
}看效果
就这么多了。用起来也很方便了。
