一个DialogFragment的封装库，提供了builder的方式进行调用，因为采用了alertDialog.Builder，所以代码中没有任何自定义，轻量稳定。
原生的Dialog提供了很多Style来让开发者进行自定义，可以满足我们百分之九十的业务需求了。这其实是Android的设计**，官方“一般”都会把属性值暴露出来，让显示和逻辑分开。因此，本项目并没有重新实现Dialog，而是通过封装了DialogFragment来让大家使用和定制Dialog更加的方便。
这里顺便贴一下dialogFragment的方法调用流程：
1.在项目外层的build.gradle中添加JitPack仓库
repositories {
maven {
url "https://jitpack.io"
}
}
2.在用到的项目中添加依赖
compile 'com.github.tianzhijiexian:EasyDialog:Latest release(<-click it)'
举例：
compile 'com.github.tianzhijiexian:EasyDialog:1.1.2'
EasyDialog充分利用了原生alertDialog.Builder的api，所以使用方式和alertDialog无异，它提供了如下五种基本的dialog。
1. 基础对话框
EasyDialog.Builder builder = EasyDialog.builder(this); // 建立builder对象
builder.setTitle("Title")
.setIcon(R.drawable.saber)
.setMessage(R.string.hello_world)
.setOnCancelListener(dialog -> Log.d(TAG, "onCancel"))
.setOnDismissListener(dialog -> Log.d(TAG, "onDismiss"))
// 设置下方的三个按钮
.setPositiveButton("ok", (dialog, which) -> {})
.setNegativeButton("cancel", (dialog, which) -> dialog.dismiss())
.setNeutralButton("ignore", null)
.setCancelable(true); // 点击空白处可以关闭
DialogFragment easyDialog = builder.build();
// 用showAllowingStateLoss()弹出
easyDialog.showAllowingStateLoss(getSupportFragmentManager());2. 单选对话框
EasyDialog dialog = EasyDialog.builder(this)
.setTitle("Single Choice Dialog")
// 这里传入的“1”表示默认选择第二个选项
.setSingleChoiceItems(new String[]{"Android", "ios", "wp"}, 1,
(d, position) -> {d.dismiss();})
.setPositiveButton("ok", null)
.build();
dialog.show(getSupportFragmentManager(), TAG);3. 多选对话框
EasyDialog.builder(this)
// 设置数据和默认选中的选项
.setMultiChoiceItems(
new String[]{"Android", "ios", "wp"}, new boolean[]{true, false, true},
(dialog, which, isChecked) -> showToast("onClick pos = " + which))
.build()
.show(getSupportFragmentManager());4. 简单列表对话框
<string-array name="country">
<item>阿尔及利亚</item>
<item>安哥拉</item>
<item>贝宁</item>
<item>缅甸</item>
</string-array>EasyDialog.builder(this)
// R.array.country为xml中定义的string数组
.setItems(R.array.country, (dialog, which) -> showToast("click " + which))
.setPositiveButton("yes", null)
.setNegativeButton("no", null)
.build()
.show(getSupportFragmentManager());自定义对话框需要继承自BaseCustomDialog。如果需要传入更多的参数，还需要继承自EasyDialog.Builder来建立自己的builder。
public class MyBuilderDialog extends BaseCustomDialog {
public static final String KEY_AGE = "KEY_AGE", KEY_NAME = "KEY_NAME";
/**
* 继承自{@link EasyDialog.Builder}以扩展builder
*/
public static class Builder extends BaseEasyDialog.Builder<Builder> {
private Bundle bundle = new Bundle();
public Builder(@NonNull Context context) {
super(context);
}
public Builder setAge(int age) {
bundle.putInt(KEY_AGE, age);
return this;
}
public Builder setName(String name) {
bundle.putString(KEY_NAME, name);
return this;
}
@NonNull
@Override
protected EasyDialog createDialog() {
MyBuilderDialog dialog = new MyBuilderDialog();
dialog.setArguments(bundle); // 增加自己的bundle
return dialog;
}
}
@Override
protected int getLayoutResId() {
return 0;
}
@Override
protected void bindViews(View root) {
}
@Override
protected void modifyAlertDialogBuilder(AlertDialog.Builder builder) {
super.modifyAlertDialogBuilder(builder);
Bundle arguments = getArguments();
String name = arguments.getString(KEY_NAME);
int age = arguments.getInt(KEY_AGE);
String str = "name: " + name + ", age: " + age;
// 修改builder对象
builder.setMessage("修改后的message是：\n\n" + str);
}
@Override
protected void setViews() {
int age = getArguments().getInt(KEY_AGE);
Toast.makeText(getContext(), "age: " + age, Toast.LENGTH_SHORT).show();
}
}在主题中设置默认样式（如果你想用原生的样式，可以跳过这个步骤）
