CustomDialog使用代码:
package com.example.iosalertview;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import com.example.iosalertview.CustomDialog.Builder;
public class MainActivity extends Activity implements OnClickListener{
private Button ios_dialog_btn,android_dialog_btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ios_dialog_btn = (Button) findViewById(R.id.ios_dialog_btn);
android_dialog_btn = (Button) findViewById(R.id.android_dialog_btn);
ios_dialog_btn.setOnClickListener(this);
android_dialog_btn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.ios_dialog_btn:
CustomDialog.Builder builder = new Builder(MainActivity.this);
builder.setTitle(R.string.prompt);
builder.setMessage(R.string.exit_app);
builder.setPositiveButton(R.string.confirm, null);
builder.setNegativeButton(R.string.cancel, null);
builder.create().show();
break;
case R.id.android_dialog_btn:
AlertDialog.Builder mbuilder = new AlertDialog.Builder(MainActivity.this);
mbuilder.setTitle(R.string.prompt);
mbuilder.setMessage(R.string.exit_app);
mbuilder.setPositiveButton(R.string.confirm, null);
