AlterDialog在Android开发中使用也比较频繁，本文就介绍了AlterDialog的几种对话框使用方式及代码解析。
使用AlerDialog 创建对话框 ：
AlertDialog.Builder builder = new AlertDialog.Builder(this);
1.设置简单的对话框
builder.setIcon(R.drawable.icon);
builder.setTitle("你确定要离开吗？");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//这里添加点击确定后的逻辑
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//这里添加点击确定后的逻辑
}
});
builder.create().show();
2.设置列表对话框
String[] mItems = {"item0","item1","itme2","item3","itme4","item5","item6"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
builder.setTitle("列表选择框");
builder.setItems(mItems, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//点击后弹出窗口选择了第几项
}
});
builder.create().show();
3.设置单选对话框
int mSingleChoiceID = -1;
builder.setIcon(R.drawable.icon);
builder.setTitle("单项选择");
builder.setSingleChoiceItems(mItems, 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
mSingleChoiceID = whichButton;
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
if(mSingleChoiceID > 0) {
// 你选择的是" + mSingleChoiceID;
}
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
builder.create().show();
4.设置多选对话框
ArrayList <Integer>MultiChoiceID = new ArrayList <Integer>();
builder.setIcon(R.drawable.icon);
builder.setTitle("多项选择");
builder.setMultiChoiceItems(mItems,
new boolean[]{false, false, false, false, false, false, false},
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int whichButton, boolean isChecked) {
if(isChecked) {
MultiChoiceID.add(whichButton);
// 你选择的为：mItems[whichButton]
}else {
MultiChoiceID.remove(whichButton);
}
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String str = "";
int size = MultiChoiceID.size();
for (int i = 0 ;i < size; i++) {
<span style="white-space:pre"> </span> str+= mItems[MultiChoiceID.get(i)] + ", ";
}
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
builder.create().show();
5.设置自定义布局对话框
View view = LayoutInflater.from(this).inflate(R.layout.custom, null);
builder.setIcon(R.drawable.icon);
builder.setTitle("自定义输入框");
builder.setView(<span style="font-family: 宋体, 'Arial Narrow', arial, serif;">view</span>);
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
EditText userName = (EditText) textEntryView.findViewById(R.id.etUserName);
EditText password = (EditText) textEntryView.findViewById(R.id.etPassWord);
// userName.getText().toString() + password.getText().toString();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
builder.create().show();
