Android 带password输入界面的Dialog实现机制

1.布局实现：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical">
    <EditText
        android:id="@+id/FactRstDialogPsw"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:password="true"
        android:singleLine="true"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_weight="2">
        <Button
            android:id="@+id/FactRstDialogCancel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:text="@string/cancel"
            android:layout_weight="1"/>
        <Button
            android:id="@+id/FactRstDialogCertain"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:text="@string/user_dict_settings_add_dialog_confirm"
            android:layout_weight="1"/>
	</LinearLayout>
</LinearLayout>

2.代码实现：

import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MasterClearConfirm extends Fragment {
	//cbk.add
	private Dialog mFactRstPwsCheckDialog;
	private Button cancelButton;
	private Button okButton;
	private EditText pswEdit;
	//cbk.add
    private Button.OnClickListener mFinalClickListener = new Button.OnClickListener() {

        public void onClick(View v) {
            if (Utils.isMonkeyRunning()) {
                return;
            }
            /// M:For CT feature resetPhone with mEraseInternalData: data | app | media 

			//cbk.add
            //mExt.onResetPhone(getActivity(), mEraseInternalData, mEraseSdCard);
			createFactoryResetPwdDialog();
			//cbk.add
        }
    };
//cbk.add
    private void createFactoryResetPwdDialog() {

		if (mFactRstPwsCheckDialog == null) {
			mFactRstPwsCheckDialog = new Dialog(getActivity());
			//mFactRstPwsCheckDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
			mFactRstPwsCheckDialog.setContentView(R.layout.factory_rst_pwd_dialog);
			mFactRstPwsCheckDialog.setTitle("please input password:");

			pswEdit = (EditText)mFactRstPwsCheckDialog.findViewById(R.id.FactRstDialogPsw);
			cancelButton = (Button)mFactRstPwsCheckDialog.findViewById(R.id.FactRstDialogCancel);
			okButton = (Button)mFactRstPwsCheckDialog.findViewById(R.id.FactRstDialogCertain);

			cancelButton.setOnClickListener(new View.OnClickListener()
			{
				@Override
				public void onClick(View source)
				{
					mFactRstPwsCheckDialog.dismiss();//finish();
				}
			});

			okButton.setOnClickListener(new View.OnClickListener()
			{
				@Override
				public void onClick(View source)
				{
					onPairPassword(pswEdit.getText().toString());
					pswEdit.setText(null);
				}
			});

		}

		if (mFactRstPwsCheckDialog != null) {
			mFactRstPwsCheckDialog.show();
		}	

    }

    private boolean onPairPassword(String value){
		//Log.d(TAG, "onPairPassword()  pwd value=" +value);
		boolean pwdvalid=false; 

		if(value ==null ){
			//Log.d(TAG, "onPairPassword()  value ==null");
			Toast.makeText(getActivity(), getString(R.string.settings_pwd_empty_str), Toast.LENGTH_SHORT).show();

			return false;
		}

		if(value.length()<=0 ){
			//Log.d(TAG, "onPairPassword()  value ==null");
			Toast.makeText(getActivity(), getString(R.string.settings_pwd_empty_str), Toast.LENGTH_SHORT).show();

			return false;
		}

		String def_pwd_value =getString(R.string.settings_pwd_def);

		//if(value.length() !=6 || isNumeric(value) ==false){
		if(value.length() < def_pwd_value.length()){
			//add the item into the Locked list.
			//Log.d(TAG, "onPairPassword()  value ==valid");
			Toast.makeText(getActivity(), getString(R.string.settings_pwd_wrong_str), Toast.LENGTH_SHORT).show();
			return false;
		}	

		//Log.d(TAG, "onPairPassword()  pwd_length =" +value.length() );

		if (value.equals(def_pwd_value)) {
			//add the item into the Locked list.
			//Log.d(TAG, "onPairPassword()  mPref.contains(PWD_PREF_NAME) ==true");
			//no store the pwd activity
			mFactRstPwsCheckDialog.dismiss();//finish();
			mExt.onResetPhone(getActivity(), mEraseInternalData, mEraseSdCard);
			return true;
		}

		Toast.makeText(getActivity(), getString(R.string.settings_pwd_wrong_str), Toast.LENGTH_SHORT).show();
		return false;
    }
//cbk.add
