Android 适应任何自定义样式 提示弹出框 Dialog 封装.doc

Android 适应任何样式 提示弹出框Dialog 封装在Android开发中，难免有各种各样的提示框，如加载数据等待框，删除确认框、输入密码提示框等等，这些是完全可以自定义的，这里给出一个框架以及一个示例，帮助你开发任何样式布局的提示框，废话不多说，直接贴代码：HintDialog.javaimport android.app.AlertDialog;import android.app.Dialog;import android.content.Context;import android.view.KeyEvent;import android.view.Window;public class HintDialogDialog mDialog = null;private Context mContext = null;private IHintDialog mIDialogInstance = null;/* * 构造函数 * param context */public HintDialog(Context context)mContext = context;mDialog = new AlertDialog(mContext)Override public boolean onKeyDown(int keyCode, KeyEvent event) if (keyCode = KeyEvent.KEYCODE_BACK & mIDialogInstance != null) mIDialogInstance.onKeyDown(keyCode, event);return true; return super.onKeyDown(keyCode, event); ;mDialog.setCancelable(false);mDialog.setCanceledOnTouchOutside(false);/* * * param iLayoutResId 此DIALOG采用的布局文件 * param interfaceInstance 此DIALOG需要实现的一些接口事件 */public void showDialog(int iLayoutResId, IHintDialog interfaceInstance)if (mDialog = null | iLayoutResId = 0) return; mIDialogInstance = interfaceInstance;mDialog.show();mDialog.setContentView(iLayoutResId);Window window = mDialog.getWindow();if (mIDialogInstance != null) mIDialogInstance.showWindowDetail(window); /* * 使dialog消失 */public void dismissDialog()if (mDialog != null & mDialog.isShowing() mDialog.dismiss(); /* * 确定Dialog是否正在显示 * return */public boolean isShowing()if (mDialog != null & mDialog.isShowing() return mDialog.isShowing(); return false;public interface IHintDialogpublic void onKeyDown(int keyCode, KeyEvent event);public void showWindowDetail(Window window);HintDialogActivity.javaimport com.example.hintdialogdemo.HintDialog.IHintDialog;import android.os.Bundle;import android.app.Activity;import android.view.KeyEvent;import android.view.Menu;import android.view.View;import android.view.Window;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;public class HintDialogActivity extends Activity implements OnClickListenerButton btnConfirm = null;HintDialog mDialog = null;Overridepublic void onCreate(Bundle savedInstanceState)super.onCreate(savedInstanceState);setContentView(R.layout.activity_hint_dialog);btnConfirm = (Button) findViewById(R.id.button1);btnConfirm.setOnClickListener(this);Overridepublic boolean onCreateOptionsMenu(Menu menu)getMenuInflater().inflate(R.menu.activity_hint_dialog, menu);return true;Overridepublic void onClick(View v)switch (v.getId()case R.id.button1:mDialog = new HintDialog( HintDialogActivity.this);mDialog.showDialog(R.layout.confirm_dialog, new IHintDialog()Overridepublic void showWindowDetail(Window window)TextView txvTitle = (TextView) window .findViewById(R.id.txvTitle);txvTitle.setText(Confirm?);Button btnOK = (Button) window.findViewById(R.id.btnOK);btnOK.setText(Yes);btnOK.setOnClickListener(HintDialogActivity.this);Button btnCancel = (Button) window .findViewById(R.id.btnCancel);btnCancel.setText(NO);btnCancel.setOnClickListener(HintDialogActivity.this);Overridepublic void onKeyDown(int keyCode, KeyEvent event)if (keyCode = KeyEvent.KEYCODE_BACK)mDialog.dismissDialog();Toast.makeText(HintDialogActivity.this, onKeyback now, Toast.LENGTH_LONG).show(););break;case R.id.btnOK:mDialog.dismissDialog();Toast.makeText(HintDialogActivity.this, Confirm OK now, Toast.LENGTH_LONG).show();break;case R.id.btnCancel:mDialog
