Dialog中Android應用中的使用方法？很多新手對此不是很清楚，為了幫助大家解決這個難題，下面小編將為大家詳細講解，有這方面需求的人可以來學習下，希望你能有所收獲。
Android開發中最常用的就是Dialog類，除了自定義dialog布局，最多的就是用在彈出對話框、進度條、輸入框、單選、復選框。
1、選擇對話框：
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setTitle("選擇對話框");
dialog.setMessage("請選擇確認或取消");
dialog.setCancelable(false); //設置按下返回鍵不能消失
dialog.setPositiveButton("確認", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "您選擇了確認", Toast.LENGTH_LONG).show();
}
});
dialog.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "您選擇了取消", Toast.LENGTH_LONG).show();
}
});
dialog.show();//顯示彈出窗口
2、進度條
ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("顯示進度條");
progressDialog.setMessage("加載中...");
progressDialog.setCancelable(true);
progressDialog.show();
3、彈出輸入框
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("彈出輸入框");
builder.setMessage("輸入內容");
final EditText editText = new EditText(this);
builder.setView(editText);
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "您輸入了" + editText.getText().toString(), Toast.LENGTH_SHORT).show();
}
});
builder.setNegativeButton("取消", null);
builder.show();
4、彈出單選框
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("彈出單選框");
final String[] choice = new String[]{"Java", "C++", "PHP"};
builder.setSingleChoiceItems(choice, 0,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "您選擇了" + choice[which], Toast.LENGTH_LONG).show();
dialog.dismiss(); // 讓窗口消失
}
});
builder.create().show();
5、彈出復選框
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("彈出多選框");
final String[] choice = new String[]{"Android", "IOS", "Windos Phone"}; // 選擇項
final boolean[] isCheck = new boolean[choice.length]; // 是否被選中
builder.setMultiChoiceItems(choice, null,
new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
if (isChecked == true)
isCheck[which] = true;
else if(isChecked == false)
isCheck[which] = false;
}
});
builder.setNegativeButton("取消", null);
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String isSelected = "您選擇了";
for (int i = 0; i < choice.length; i++) {
if (isCheck[i] == true) {
isSelected += choice[i]+","; // 將選擇的內容加上
}
}
Toast.makeText(MainActivity.this, isSelected, Toast.LENGTH_LONG).show();
}
});
builder.create();
builder.show();
6、自定義布局的Dialog
AlertDialog.Builder builder = new AlertDialog.Builder(this);
final AlertDialog dialog = builder.create();
View view = View.inflate(this, R.layout.personal_modifyhead_dialog, null);
dialog.setView(view, 0, 0, 0, 0);// 設置邊距為0,保證在2.x的版本上運行沒問題
dialog.show();
AutoRelativeLayout rl_photograph = (AutoRelativeLayout) view.findViewById(R.id.rl_photograph);
rl_photograph.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
presenter.modiftHeadFromPhotograph();
dialog.dismiss();
}
});
AutoRelativeLayout rl_album = (AutoRelativeLayout) view.findViewById(R.id.rl_album);
rl_album.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
presenter.modifyHeadFromAlbum();
dialog.dismiss();
}
});
