Dialog总结
AlertDialog.Builder AlertDialog Dialog辨析
Dialog implements DialogInterface, Window.Callback,KeyEvent.Callback, OnCreateContextMenuListener, window.OnWindowDismissedCallback
AlertDialog extends Dialog implements DialogInterface {
public static class Builder {}
}
一,谷歌建议使用之类AlertDialog ,不建议直接使用Dialog 。
二,AlertDialog.Builder是用来创建AlertDialog ,并简化设置参数的工具类,可直接用连续的"."符号设置参数。
如:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
TextView tv = new TextView(builder.getContext());
tv.setText("haha");
builder.setTitle("aaa")
.setView(tv)
.show();

AlertDialog.Builder 的api
/**
* Creates an {@link AlertDialog} with the arguments supplied to this
* builder.
* <p>
* Calling this method does not display the dialog. If no additional
* processing is needed, {@link #show()} may be called instead to both
* create and display the dialog.
*/
public AlertDialog create() {
// Context has already been wrapped with the appropriate theme.
final AlertDialog dialog = new AlertDialog(P.mContext, 0, false);
P.apply(dialog.mAlert);
dialog.setCancelable(P.mCancelable);
if (P.mCancelable) {
dialog.setCanceledOnTouchOutside(true);
}
dialog.setOnCancelListener(P.mOnCancelListener);
dialog.setOnDismissListener(P.mOnDismissListener);
if (P.mOnKeyListener != null) {
dialog.setOnKeyListener(P.mOnKeyListener);
}
return dialog;
}

/**
* Creates an {@link AlertDialog} with the arguments supplied to this
* builder and immediately displays the dialog.
* <p>
* Calling this method is functionally identical to:
* <pre>
* AlertDialog dialog = builder.create();
* dialog.show();
* </pre>
*/
public AlertDialog show() {
final AlertDialog dialog = create();
dialog.show();
return dialog;
}
半自定义Dialog View的两种方法
注:并非自定义view,而是利用Dialog本身提供的api进行自定义。
AlertDialog
public static void showSimpleDialog(Context context, String msg, View.OnClickListener listener) {
final AlertDialog.Builder builder = new AlertDialog.Builder(context);
final AlertDialog dialog = builder.create();
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.dialog_simple_deposit, null);
TextView tvConfirm = (TextView) view.findViewById(R.id.tv_confirm);
tvConfirm.setOnClickListener(listener);
tvConfirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
TextView tvMsg = (TextView) view.findViewById(R.id.tv_msg);
tvMsg.setText(msg);
dialog.setView(view);
dialog.setCancelable(false);// 返回键不可取消
dialog.setView(view, 0, 0, 0, 0);// 可消除部分边框,当不能全部消除
dialog.show();
}
--------------------------------------
Dialog
public static void showSimpleDialog1(Context context, String msg) {
final Dialog dialog =new Dialog(context, R.style.dialog);// 可以消除黑色边框
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.dialog_simple_deposit, null);
TextView tvConfirm = (TextView) view.findViewById(R.id.tv_confirm);
// tvConfirm.setOnClickListener(listener);
tvConfirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
TextView tvMsg = (TextView) view.findViewById(R.id.tv_msg);
tvMsg.setText(msg);
dialog.setContentView(view);
dialog.setCancelable(false);// 返回键不可取消
dialog.show();
}
