1.創建對象框
AlertDialog.Builder builder = new Builder(context);
builder.setTitle("請輸入"); //設置對話框標題
builder.setIcon(android.R.drawable.btn_star); //設置對話框標題前的圖標
2.創建EditText輸入框
final EditText edit = new EditText(context);
3.將輸入框賦值給Dialog,並增加確定取消按鍵
builder.setView(edit);
builder.setPositiveButton("確認", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "妳輸入的是: " + edit.getText().toString(), Toast.LENGTH_SHORT).show();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "妳點了取消", Toast.LENGTH_SHORT).show();
}
});
4.設置常用api，並show彈出
builder.setCancelable(true); //設置按鈕是否可以按返回鍵取消,false則不可以取消
AlertDialog dialog = builder.create(); //創建對話框
dialog.setCanceledOnTouchOutside(true); //設置彈出框失去焦點是否隱藏,即點擊屏蔽其它地方是否隱藏
dialog.show();
