自定義View-AlterDialog

自定義View-AlterDialog

UI有些醜，各位見諒啊🤣

自定義AlterDialog主要是自定義Builder

現在定義一個類繼承AlterDialog，這裏只是爲了給Builder提供一個外部類，其實只是自定義一個Builder也是可以的

public class FxAlterDialog extends AlertDialog {

    protected FxAlterDialog(@NonNull Context context) {
        this(context, 0);
    }

    protected FxAlterDialog(@NonNull Context context, int themeResId) {
        this(context, false, null);
    }

    protected FxAlterDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
    }
}

寫內部類Builder

public static class Builder extends AlertDialog.Builder {
        private View mContainerView;
        private Context mContext;

        private Button btnCancel;

重點在於下面幾個方法，爲了屏蔽以及重寫父類的方法，防止調這些方法時執行父類的方法內容

@Override
public Builder setNegativeButton(CharSequence text, OnClickListener listener) {
    return this;
}

@Override
public Builder setView(View view) {
    return this;
}

@Override
public Builder setTitle(int titleId) {
    this.setTitle(mContext.getResources().getString(titleId));
    return this;
}

@Override
public Builder setTitle(CharSequence s) {
    mTvTitle = mContainerView.findViewById(R.id.tv_title);
    mTvTitle.setVisibility(View.VISIBLE);
    mTvTitle.setText(s);
    return this;
}

@Override
public Builder setMessage(int messageId) {
    this.setMessage(mContext.getResources().getString(messageId));
    return this;
}

@Override
public Builder setMessage(@Nullable CharSequence message) {
    mTvMessage = mContainerView.findViewById(R.id.tv_message);
    mTvMessage.setVisibility(TextUtils.isEmpty(message) ? View.GONE : View.VISIBLE);
    mTvMessage.setText(message);
    return this;
}

@Override
public AlertDialog create() {
    mDialog = super.create();
    return mDialog;
}

@Override

    initContentView();
    mDialog.show();
    return mDialog;
}
