就是要打字，怎麼樣之 AlertDialog & EditText

AlertDialog能夠勾選，這麼簡單的的程式，隨便寫寫就OK了，再來要寫些甚麼呢?就再弄個其他的樣式來看看吧，讓跳出來的畫面可以打字吧!!!

1. 建立專案

2. 加個Button

3. Source Code

package com.example.ex004; import android.os.Bundle; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TextView; public class MainActivity extends Activity {      private TextView tv;      private Button btn;           @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.activity_main);                   tv = (TextView) MainActivity.this.findViewById(R.id.textView1);          btn = (Button) MainActivity.this.findViewById(R.id.button1);          final LinearLayout ll = new LinearLayout(this);          final EditText et = new EditText(this);          ll.setOrientation(LinearLayout.VERTICAL);          ll.addView(et);          btn.setOnClickListener(new Button.OnClickListener() {               @Override               public void onClick(View v) {                   // TODO Auto-generated method stub                   new AlertDialog.Builder(MainActivity.this)                            .setTitle("EX004")                            .setView(ll)                            .setPositiveButton("OK",                                      new DialogInterface.OnClickListener() {                                          @Override                                          public void onClick(DialogInterface dialog,                                                   int which) {                                               // TODO Auto-generated method stub                                               tv.setText(et.getText());                                          }                                      })                            .setNegativeButton("Cancel",                                      new DialogInterface.OnClickListener() {                                          @Override                                          public void onClick(DialogInterface dialog,                                                   int which) {                                               // TODO Auto-generated method stub                                          }                                      }).show();               }          });               }      @Override      public boolean onCreateOptionsMenu(Menu menu) {          // Inflate the menu; this adds items to the action bar if it is present.          getMenuInflater().inflate(R.menu.main, menu);          return true;      } }

 
4. 按個按鈕吧

5. 就是這個框

6. 感動吧!再按一次

7. 蝦密，掛了
